Question

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

Answer 1

Answer:

x = 36

Step-by-step 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.
