SSS

Step-by-step explanation:

In the given picture , we have given two triangle with one common side and 2 pairs of corresponding equal sides as 7 units and 8 units.

Therefore, all the corresponding three sides of both the triangles are equal.

Hence, by SSS postulate of congruence both triangles are congruent.

SSS postulate says that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

the answer is 99.
