Given triangle ABC congruent to triangle PQR, m angle B = 3v + 4, and m angle Q = 8v - 6, find m angle B and m angle Q

A. 22

B. 11

C. 10

D. 25

Take a look at the order of the letters of ur triangles.

ABC and PQR ... it says they are congruent ... so they r equal.

And the order of the letters means : < A = < P, and < B = < Q, and < C = < R.

so if < B = < Q ... set them equal to each other and solve for v

3v + 4 = 8v - 6

6 + 4 = 8v - 3v

10 = 5v

10/5 = v

2 = v

now we sub our 2 in for v

< B = 3v + 4 ... 3 (2) + 4 = 10

< Q = 8v - 6 ... 8 (2) - 6 = 10

so < B and < Q both equal 10 <==
