Question 465168: in the ff. angle 5 and angle 7 are supplementary give the measure of each angle
1.) measure angle 5 = 2x
measure angle 7 = 4x
2.) measure angle 5 = x + 10
measure angle 7 = 2x + 20

in the ff. angle 5 and angle 7 are supplementary give the measure of each angle
1.) measure angle 5 = 2x
measure angle 7 = 4x
---
Equation:
2x+4x = 180
6x = 180
x = 30
angle 5 = 2x = 60 degrees
angle 7 = 4x = 120 degrees
=======================================
2.) measure angle 5 = x + 10
measure angle 7 = 2x + 20
Equation:
x+10 + 2x+20 = 180
3x = 150
x = 50
angle 5 = x+10 = 60 degrees
angle 7 = 2x+20 = 120 degrees
======================================
