Answer:
37°
Step-by-step explanation:
ΔOPQ extended trough Q to R
m∠PQR = (7x-19)° -is an exterior angle to the triangle
m∠OPQ = (2x-3)° -angle inside the triangle
m∠QOP = (x+16)° -angle inside the triangle
m∠PQR = ?
m∠PQR = m∠OPQ + m∠QOP
7x-19 = 2x-3 +x+16
7x -2x-x = 16-3+19
4x = 32
x=32/4=8
m∠PQR = 7x-19 = 7*8-19 =56 -19= 37°
