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 <==
Answer:
73
Step-by-step explanation:
When you have a line intersecting another line, the angles produced by the intersection will be equal to 180.
This means that (-39 + x) + 146 = 180. Solve for x.
(-39 + x) + 146 = 180
-39 + x = 34
x = 73
