40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
Answer:

Step-by-step explanation:
Given the function

We can find the inverse function by exchanging x and y, and then solve for y.

Replace x with y.

square both sides


Hence,

3/4x - 16 = 28
+16 +16
3/4x = 44
*3/4 *3/4
x = 176/3
Answer:
21,316! hope that helps lol
Answer:
x = 27
Step-by-step explanation:
Given
= 3
Multiply both sides by 9 to clear the fraction
x = 9 × 3 = 27
