Question

Can someone show me the work they have that gets the answers to these problems?

Answer 1

x = 36

Explanation:

The triangles are similar. Thus, the following equation of ratios is true:

x 45

------ = ------

16 20

and so 20x = 16(45) = 720.

Dividing both sides by 20, we get x = 720/20 = 36.
