PLEASE HELPPP WILL GIVE BRAINLIEST!!!

Given:

The sides of each brace have lengths 63 feet, 46 feet, and 40 feet.

To find:

The measure of the angle opposite the 46 foot side.

Solution:

According to the Law of Cosines:

[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]

We need to find the measure of the angle opposite the 46 foot side. So, [tex]a=46[/tex] and the other sides are [tex]b=63,c=40[/tex].

[tex]\cos A=\dfrac{(63)^2+(40)^2-(46)^2}{2(63)(40)}[/tex]

[tex]\cos A=\dfrac{3969 +1600-2116}{5040}[/tex]

[tex]\cos A=\dfrac{3453}{5040}[/tex]

[tex]\cos A=\dfrac{1151}{1680}[/tex]

Taking cos inverse on both sides, we get

[tex]A=\cos^{-1}\dfrac{1151}{1680}[/tex]

[tex]A=46.75503[/tex]

[tex]A\approx 47[/tex]

Therefore, the measure of the angle opposite the 46 foot side is 47 degrees.

Answer: (x,y) has the meaning of plane's point coordinates. The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a complex number: x is the real part and y is the imaginary part: x+yi.

Answer:

2.7 kb

Step-by-step explanation:

Total kb = 7.48

Total apps = 2

one app = 4.78

another app = x

> 4.78 + x = 7.48

x = 7.48 – 4.78

= 2.7 kb

Kindly check explanation

Step-by-step explanation:

Using visual comparison :

SHAPE :

Both plots are fairly left skewed as their peaks are more shifted to the right and tails to the left of the distribution.

The centre :

Both softball and basketball plots are centered around the median of the distribution. With softball having a centre (median value) of 5'4'' and basketball has a value of 5'8''.

Spread :

The softball plot spread from 4'9'' through 5'6''

While basketball spreads from 5'2'' through 6'0''

Answer:

46%

Step-by-step explanation:

divide 12 by 26

Answer:

2x - (0.50x + 18) = profit

Step-by-step explanation:

x = number of carnations, for example if 3 carnations were sold, $6 from sales - (1.50 + 18) = profit. The 50 cents from each carnation that they bought to sell, plus 18 delviery fee. Hope this helped! Good luck!

Answer:

Omg where is it then

Step-by-step explanation:

upload image attachment

Answer:

First we can do (12*4)- thats the top rectangle. Remember area is base times height.

48

Next lets do (8*12)-thats the middle rectangle

48+ 96

Now the triangles.

you can just do 2*8/2 because a triangle is half of a rectangle.

48+ 96+ 8

add 8 again because theres 2 triangles-

48+96 + 8 +8

Your answer is 160

I hope this helps you!

Goodluck!

Answer:

8 has to be included in the data set. Since 8 is the mode, and the mode is the number that is seen the most in a set of numbers, 8 has to be in the data set for it to be the mode. Therefore, the answer is 8.

Answer:

No the student is not correct because the answer is 0.4761. All the student did was wrong was the adding up the zeros.

Answer:

Scale factor = 4

Step-by-step explanation:

Scale factor = [tex]\frac{\text{Dimension of the larger (Image) triangle}}{\text{Dimension of the smaller (Preimage) triangle}}[/tex]

From the given triangle,

Length of one side of the larger triangle = 8 units

Length of the corresponding side of the smaller triangle = 2 units

By substituting the values in the formula of scale factor,

Scale factor = [tex]\frac{8}{2}[/tex]

Scale factor = 4

Answer:

you would need to add the like terms together

Step-by-step explanation:

Answer:

x = 47°

Step-by-step explanation:

From the picture attached,

CPD is a straight line.

Therefore, ∠CPB and ∠DPB is a linear pair of angles.

And linear pair of angles are supplementary.

By the property of linear pair of angles,

m∠CPB + m∠DPB = 180°

133 + x = 180

x = 180 - 133

x = 47°

Answer:

The answer is 20/30 or in simplified form 2/3

Step-by-step explanation:

The way I do it is I take the probability of blue flashlights, 18/30, added to the probability of black flashlights, 2/30. Then, you simplify by dividing both numbers by 10.

HOPE THIS HELPED!!!

Answer:

[tex]\huge\boxed{\boxed{12a-60}}[/tex]

Step-by-step explanation:

Hello.

The Distributive Property states that

a(b+c)=ab+ac

Where

a, b, and c can be either constants or variables

we distribute a by multiplying it times b and c, and simplify if necessary.

In this case, we should distribute 12:

12(a-5)

12 times a and 12 times (-5):

12a-60

And we're done!

I hope it helps & have an outstanding day!
