Question

Given that ARSTandARQW are right triangles, what value of x proves that the two triangles are similar? 70 ft 5.7 ft 25.2 11 8 ft

Answer 1

Ratio from one side:

Small triangle = 12ft

Big triangle = 42

Ratio: 42/12 = 3.5

So divide the height of the big triangle by the ratio to obtain the value of x:

20/3.5 = 5.7 ft
