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 PQRit says they are congruentso they r equal.
And the order of the letters means : < A = < P, and < B = < Q, and < C = < R.

so if < B = < Qset 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 + 43(2) + 4 = 10
< Q = 8v - 68(2) - 6 = 10

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