Question

Solve for x. The polygon in each pair are similar.

Answer 1

x = 6

Explanation:

If polygons are similar then the side lengths are proportional, so we can write the following equation to find the value of x:

15/6 = (5x + 10)/16 cross multiply fractions

240 = 30x + 60 subtract 60 from both sides

180 = 30x divide both sides by 30

6 = x
