Question

If p||q and angle 1=2x+90, angle 6 =70-x,then find the measure of angle 4 and angle 8​

Answer 1

Step-by-step explanation:

angle 1 = angle 5 (corresponding angles)

angle5+angle6= 180( linear pair)

so 2x+90+70-x=180

x+160=180

x= 180-160=20

x=20

so angle 6= 70-20= 50

angle 6 = angle 8 (vertically opposite angles)

angle8 = angle 4(corresponding angles)
