Answer:
see below
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles.
139 = <Q + <P
= 6y+1 + 4y+8
= 10y+9
139 = 10y+9
Subtract 9 from each side
130 = 10y
Divide each side by 10
13 = y
<P = 4y+8 = 4*13+8 = 60
<Q = 6y+1 = 6*13+1 =79
QPR = We know this makes a straight line with 139
= 180-139 = 41
