Answer:
A.15
Explanation:
These two triangles are congruent triangles. This means that the side measurements can be found through a single multiplicative number.
All you have to do is divide 49 by 23 and get 2.130434783. You need that number to be specific
Next you want to multiply that number by the side length that corresponds to the length you are trying to find. In this case that is 7.
7 x 2.130434783=14.9
14.9 rounds to 15
