2 problems:
1. Are we dealing with a triangle PQR ?
2. What is mPR mean? Is it perhaps ∠P ?
If it is a triangle and we know angle two angles,
then we know that the sum of all 3 angles is 180°
so my guess is that you mean:
12x-2 + 20x-10 + third angle = 180°
further information is needed to find x
If m∠PQR=(12x−2)∘, and mPR=(20x−10)∘, what is m∠PQR?
answer choices are:
a. 137.5
b. 70
c. 16
d. 81
