Question

Solve similar triangles

Answer 1

22.5

Explanation:

With similar triangles you don't have to solve for any angle, as both triangles are alike, just different sizes in the case. So 20/12 = 5/3 or 1.66, and the same for 27.5/16.5, so using that, we have 37.5/1.66 which is 22.5

Answer 2

y=27.5 is the answer
