You could reverse the triangle to look like a regular right triangle, making 7 on the bottom and 15 as the hypotenuse.
The height is about 13.2664991614216, which is rounded to 13
As long as we know the base and the hypotenuse we can calculate the value of x. If you do the math you get 62.181860715346076° which is rounded to 62°

The answer is 62°

Answer:

26.3 rev/min

Step-by-step explanation:

The angular velocity (ω) is the linear velocity divided by the radius ( r= 80 feet)

ω = 220/80 = 2.75 rad/s

The angular velocity and the frequency are related by:

ω = 2π*f

2.75 = 6.28*f

f = 2.75/6.28

f = 0.438 rev/s * 60s/1min

f = 26.3 rev/min

Find the scale factor.

aivan3 [116]

The scale factor is 1.5. The dilation rule is : (x,y)-------(.15x,1.5y)

Step-by-step explanation:

Dilation is a transformation that maps an object to an image of the same shape as the original object to form a different size image.When a larger image is produced it's called an enlargement where as when a small image is produced, it's called a reduction.

The rule of dilation, with center as the origin follows;

(x,y)------(sx,sy) where s is the scale factor. To find the scale factor, select one of the vertices of the object and of the image at divide the coordinate of image with that of object.

Taking O(2,16) and O'(3,24), the scale factor will be;

s*2=3

2s=3

s=3/2 =1.5

s*16=24

16s=24

s=24/16=3/2=1.5

The scale factor is 1.5, hence the dilation rule is;

(x,y)-------(.15x,1.5y)
