The angle 01 is located in Quadrant IV, and sin(01) = -24/ 25

What is the value of cos(01)?​

Answers

Answer 1

Answer:

[tex] \frac{7}{25} [/tex]

Step-by-step explanation:

We can solve that using this identity,

[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]

plug in -24/25 from x in sin

[tex] \sin {}^{2} ( \frac{ - 24}{25} ) + \cos {}^{2} (x) = 1[/tex]

[tex] \sin( \frac{576}{625} ) + \cos {}^{2} (x) = 1[/tex]

[tex] \cos {}^{2} (x) = 1 - \frac{576}{625} [/tex]

[tex] \cos {}^{2} (x) = \frac{49}{625} [/tex]

[tex] \cos(x) = \frac{7}{25} [/tex]

Since cos is positve in quadrant 4, the answer is 7/25.

Answer 2

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

then

Sin(Ф) = - [tex]\frac{24}{25}[/tex]

find the angle Ф

Ф = arcSin ( - [tex]\frac{24}{25}[/tex] )

Ф = -73.739795°

so an angle measured clock wise from x axis at zero°

now use cos(Ф) = x/ 25    to find x

25* cos(  -73.739795°) = x

7 = x   :o  wow... exactly?   :P nice

cos(Ф) = 7/25     I think that's what they wanted to know  

also I noted my calculator tried to find the fraction of 0.2800000049 and couldn't,  but then I just put in 0.28 and it found that to be 7/25  :0  so I think we're spot on  :)

Answer:

Adding 12 to the circle area is equal to the square area.

Or

s2 = 12 + A

Where

s = side of square

A = area of circle

So

s2 = 12 + 36

s2 = 48

Solve this for s to get the side length

Solve for x. 6x-20 4x+50

Answers

Answer: Simplifying

4x + 50 = 6x + 20

Reorder the terms:

50 + 4x = 6x + 20

Reorder the terms:

50 + 4x = 20 + 6x

Solving

50 + 4x = 20 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

50 + 4x + -6x = 20 + 6x + -6x

Combine like terms: 4x + -6x = -2x

50 + -2x = 20 + 6x + -6x

Combine like terms: 6x + -6x = 0

50 + -2x = 20 + 0

50 + -2x = 20

Add '-50' to each side of the equation.

50 + -50 + -2x = 20 + -50

Combine like terms: 50 + -50 = 0

0 + -2x = 20 + -50

-2x = 20 + -50

Combine like terms: 20 + -50 = -30

-2x = -30

Divide each side by '-2'.

x = 15

Simplifying

x = 15

Look at thee isosceles triangle what angle is B?
(I am so so tired is 2 in the morning)

Answers

Isosceles means the bottom right angle is also 65, so to add up to 180, the final angle (B) must be 50.

Answer:

m∡b = 50°

Step-by-step explanation:

this is an isosceles triangle so the other base angle also measures 65°

there are 180° in a triangle so m∡b = 180-(65+65) or 50°

5 hours 19 minutes 18 seconds

Step-by-step explanation:

Given :

28/4/18:

Time : 1 :03 : 25

Fastest mile = 02 : 25

Distance = 15.05 miles

03/5/18:

Time : 2:06: 41

Fastest mile = 02 : 53

Distance = 28.70 miles

08/5/18:

Time : 2 :09:12

Fastest mile = 02 : 45

Distance = 26.39 miles2

1.) shortest distance cycled :

From the data:

15.05 < 26.39 < 28.70

Shortest distance cycled = 15.05 miles

The longest the cycled:

1 :03 : 25 < 2:06: 41 < 2 :09:12

Longest = 2 :09:12

Total cycling time :

1 :03 : 25 + 2:06: 41 + 2 :09:12

(1 + 2 + 2)= 5 hrs

(03 + 06+ 09) = 18 minutes

(25 + 41 + 12) = 78 seconds = 1 minute 18 seconds

18 minutes + 1 minute = 19 minutes

Total = 5 hours 19 minutes 18 seconds

Answer:

468 Square Centimeters

Step-by-step explanation:

Surface area can be calculated by adding the areas of each face on a prism:

The rectangle to the left is a 9 by 10. The formula for the area of a rectangle is length times width, so we can get the area by multiplying 9 and 10: 9*10=90To the right of that rectangle is another rectangle. This time it's a 10 by 12, as we can see in the picture. Multiply 10 and 12: 10*12=120The last rectangle, on the right, is a 15 by 10. Multiply 15 and 10: 15*10=150Now look at the triangle on the top. The formula for the area of a triangle is base times height divided by 2. The base of the triangle in this case is the bottom side, 12. The height is how tall the triangle is, 9. Multiply 9 and 12: 9*12=108. Divide that by 2: 108/2=54Finally, look at the triangle on the bottom. It is exactly the same as the one on the top, with a base of 12 and a height of 9. Since it is exactly the same, we know that it has the same area too: 54Add up the areas: 90+120+150+54+54=468

Answers

Answer:

Step-by-step explanation:

base = 784 sq in²  28 in tall pyramid

each side of the square base = √784   also equals 28

using the Pythagorean theorem the length of each side of the pyramid from the base to the point is

(side/2)² + height² =( length of the pyramid face)²

(28/2)² + 28²  = 196 + 784  = 980 =  (face length)²

face length = √980    =  31.3

area of the pyramid = 4 sides × area of each face + the area of the base

    =   4×[(1/2)(base)(face length)] + side²

    =   4(1/2)(28)(31.3) + 784

    =   2537 sq in²     Not in the solution set
