Add 7 on both sides to then left side cancels out and you end up with 13x=143 then you divide 13 on both sides and get x=11
Because 3/4 = 9/12, anything such as 10/12, 11/12, and maybe even 12/12 will work.
The answer is C. See the work below.
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°
