<h3>Answer: B) 10.3</h3>

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(20) = x/11

11*cos(20) = x

x = 11*cos(20)

x = 10.336618828645

x = 10.3

Make sure your calculator is in degree mode.

Find the inverse of the function given? f(x) =x+9/2

tekilochka [14]

Answer: f^ -1 = x-9/2
Explanation & Steps:
1) Change f(x) to y
2) Switch y and x -> you will get x= y + 9/2
3) subtract 9/2 on both sides -> you will get x-9/2= y

Result- y = x-9/2
(Switch y to f^-1)
Hope this helps :)
