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
