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

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.
