Angle XYZ = 2X° and angle PQR = (8X -20)°. If angle XYZ and angle PQR are supplementary, find the measure of each angle. Angle P
Alchen [17]

Answer:

PQR = 140

Step-by-step explanation:

Given

XYZ = 2X

PQR = 8X - 20

Required

Find PQR

Since both angles are supplementary, we have:

XYZ + PQR = 180

This gives:

2X + 8X - 20 = 180

10X - 20 = 180

Collect Like Terms

10X = 20 + 180

10X = 200

Divide through by 10

X = 20

Substitute 20 for X in PQR = 8X - 20

PQR = 8 * 20 -20

PQR = 140
