Answer:
C
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
1) Substitute the values of t, v, and w into the expression:
2) Simplify the terms:
If triangle MNP is congruent to triangle QST, that means that M and Q are congruent, N and S, and P and T, as they are in order, respectively. This means that the measure of angle S is the same as the measure of angle N, which is 78º. Therefore, the measure of angle S is 78º.
