Answer: B) 180°
Step-by-step explanation:
Angle P and Q forms a straight line which means they add up to 180 degrees.
So angle P is 50 degrees then we need to find it's supplement.
Using the equation 50 + x = 180 we can solve for x to find the supplement.
50 + x = 180 subtract 50 from both sides
-50 -50
x = 130
