Question

The triangles are similar. Find the value of x. Round to the nearest tenth.

(Please help!)​

Answer 1

28.3

Explanation:

The triangles are similar, so we can use the scale factor to calculate the value of x:

12/20 = 3/5 is the scale factor

17/x = 3/5 cross multiply expressions

85 = 3x divide both sides by 3

28.3 = x approximately
