Question

Ind the missing length. The triangles are similar. similar 16 A. 27 B. 24 C. 16 D. 21

Answer 1

You haven’t given any other information, but here’s how to go about it:

Find the ratio of one pair of corresponding sides of the two triangles. Use this ratio to find the missing side length.

For example if one triangle A has the side lengths 5, 10, and 13 and the other similar triangle B has known side lengths of 10, 20 and one of the side lengths is missing, then the ratio of the corresponding side lengths of B to A is 10:5 or 20:10 which is 2. So corresponding sides in triangle B are 2 times the length of those in A, which means the missing side length in B is 13*2= 26.

I hope this helps you understand how to solve your problem.
