in triangle PQR, the measure of angle P=53degrees, PQ=7.4, and PR=9.6. what is the measure of angle R to the nearest degree?

a. 61 degrees

b. 49 degrees

c. 42 degrees

d. 35 degrees

Answer:

60%

Step-by-step explanation:

184 - 115 = 69

[tex]\frac{69}{115} =.6\\\\[/tex]

.6 × 100 = 60%

115 + 60% = 69

Answer:

AD and BE is perpendicular => angle BED = 90 deg.

Otherwise angle CED = arc CD = 30 deg

=> angle BEC = angle BED - angle CED = 90 - 30 = 60 deg

Suppose a, b and c are 3 sides of a triangle in which a < b < c.

As property of length of sides a, b, and c of a triangle:

c - b < a < c + b

b - a < c < b + a

c - a < b < c + a

=> 6.7 inches, 1.1 inches, and 7.9 inches are not sides of a triangle

Check:

7.9 - 1.1 < 6.7 <=> 6.8 < 6.7  <=> invalid!

Hope this helps!

Answer:

On the first equation, which is (c-d)/5 - 2 = 0 Let's start by solving c.

First, you need to add 1/5d to both sides:

1/5 c + -1/5 d - 2 + 1/5 d = 0 + 1/5 d

1/5 c - 2 = 1/5 d

Next, add 2 to both sides:

1/5 c - 2 + 2 = 1/5 d + 2

1/5 c = 1/5 d + 2

Now, divide both sides by 1/5:

1/5 c/ 1/5 = 1/5 d + 2/ 1/5

c = d + 10

so, therefore, your answer is c = d + 10

____________________________________________________________

Now we are going to do the 2nd equation, which is c-6d=0 Lets solve c.

The only thing you need to do is you need to add 6d to both sides:

c − 6d + 6d = 0 + 6d

c = 6d

So, therefore, your answer is c = 6d

Answer:

BXBXBXBXBXB

Step-by-step explanation:

The term without exponent is b*b*b*b*b*b,

B:  (b³)² = b⁶.

The formula for an exponential function is f (x) = aˣ, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.

Given the term (b³)²

we know a² = a*a

so (b³)² = b³*b³

and a³ = a*a*a

(b³)² = b³*b³ = b*b*b*b*b*b

so (b³)² without exponent is b*b*b*b*b*b

and we know (aⁿ)ˣ = aⁿˣ

(b³)² = b⁶

Hence term without exponent is  b*b*b*b*b*b and compared power is b⁶.

Answer:

  about 11.856 time units

Step-by-step explanation:

We have to assume the equation has something to do with the path of the ball relative to the ground. Perhaps it represents height, with t representing time. The height (h) will be zero for the values of t that satisfy ...

  0 = -t^2 +10t +22

Using the quadratic formula, we can find the values of t that satisfy this equation:

  t = (-10 ±√(10² -4(-1)(22)))/(2(-1)) = (-10 ±√188)/-2 = 5±√47

The value of h is zero for t ≈ 11.856.

About the quadratic formula

The quadratic formula tells you the solution to ...

Answer:

[tex](3,29)[/tex]

Step-by-step explanation:

There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is [tex]x=\frac{-b}{2a}[/tex]

We have the function [tex]g(x)=-3x^2+18x+2[/tex]

From this function, we can find that

[tex]a=-3\\b=18\\c=2[/tex]

We can plug in our know values into the formula to get

[tex]x=\frac{-18}{2(-3)\\} \\x=\frac{-18}{-6} \\\\x=3[/tex]

Then we can plug in our x-value to find the y-value of the vertex

[tex]g(3)=-3(3)^2+18(3)+2\\\\g(3)=-3(9)+54+2\\\\g(3)=-27+54+2\\\\g(3)=29[/tex]

This means that the vertex would be [tex](3,29)[/tex]

Step-by-step explanation:

1. Answer (D). By the law of sines, we have [tex]\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}[/tex] in any [tex]\triangle ABC.[/tex]

2. Answer (C). The law of cosines, [tex]c^2=a^2+b^2-2ab\cos C,[/tex]accepts up to three sides and an angle as an input.

3. Answer (D). Although this triangle is right, we are not given enough information to uniquely determine its sides and angles - here, we need either one more side or one more angle.

4. Answer (D). Don't get tripped up by answer choice (C) - this is just a rearrangement of the statement of the law of cosines. In choice (D), the signs of [tex]a^2[/tex] and [tex]2ab\cos C[/tex] are reversed.

5. Answer (B). By the law of sines, we have [tex]\frac{5}{\sin 40^\circ}=\frac{3}{\sin\theta}.[/tex] Solving gives [tex]\theta\approx \boxed{23^\circ},157^\circ.[/tex] Note that this is the ambiguous (SSA) case of the law of sines, where the given measures could specify one triangle, two triangles, or none at all!

6. Answer (A). Since we know all three sides and none of the angles, starting with the law of sines will not help, so we begin with the law of cosines to find one angle; from there, we can use the law of sines to find the remaining angles.

Answer:

523.8 miles

Step-by-step explanation:

The drawing attached represents the question. We create a triangle with the distances from each pair of cities, and we call the distance from B to C by 'd'.

First, we need to find the angle BAC:

55° + BAC + 7° = 90°

BAC = 28°

Then, we can use the law of cosines to find the value of d:

d^2 = 470^2 + 890^2 - 2*470*890*cos(BAC)

d^2 = 470^2 + 890^2 - 2*470*890*0.8829

d^2 = 274365.86

d = 523.8 miles

Answer:

16.5 ft

Step-by-step explanation:

Circumference is 2πr, so radius being 5.25/2 would calculate to 16.5

Answer:

Option A

radius = 13 units

height = 20 units

Volume of the cylinder = πr²h

= π (13)² ×20

=3380π cu. units

The volume of the cylinder will be 3380 π cubic units. Then the correct option is A.

Let r be the radius and h be the height of the cylinder.

Then the volume of the cylinder will be

V = π r²h cubic units

The radius is 13 and height is 20.

Then the volume of the cylinder will be

V = π (13)² x 20

V = 3380 π cubic units

Then the correct option is A.

Answer:

9,670

Step-by-step explanation:

8,219.5 ÷ 85% (0.85) = 9,670

The height of the volcano is reduced after the eruption, then the original height of the volcano is 9670 feet.

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given information in the question,

Height of the volcano after eruption = 8,219.5 feet

Let the original height of the volcano is x.

85% of x = 8219.5

x = (8219.5 × 100)/85

x = 9670 feet.

Now with the rest of the money you can download 4 albums.

4 individual songs, 4 albums.

0.25x4+4x2

12 individual songs, 3 albums

Answer:

x=28

Step-by-step explanation:

The interior angles of a triangle must add to 180 degrees.

Therefore,

x+95+57=180

Add 95 and 57

x+152=180

We are trying to find x. In order to do this, we must get x by itself. 152 is being added to x. The opposite of addition is subtraction. So subtract 152 from both sides.

x+152-152=180-152

x=180-152

x=28

Let’s check our answer. Add all the angles together, to be sure they add to 180 degrees.

x+95+57=180

Substitute 28 for x

28+95+57=180

180=180

The equation above is true, so we know that x is equal to 28.

____________________________________

Hey!!

Solution:

X+95+57=180 (sum of angle in triangle)

or,X+152=180

or,X=180-152

X=28 degree.

The value of X is 28 degree.
