The accompanying diagram shows two triangles. Which proportion could be used to solve for x ?

Answers

Answer:
A) 32/x=12/15

Explanation:
When we compare 32/x, we’re looking the ratio between the two side lengths on the first triangle. When we compare 12/15, we’re looking at the ratio between the two side lengths on the second triangle. These ratios must be equal to each other since the two triangles are similar, and we can use this to solve for x.

Answers

Answer:

61
