Question

In a figure ab parallel cb and l is the transvesal if angle2=2multiplied angle 1 then find the measure of angle 7

Answer 1

Answer:

Angle 7 = 60 degree

Step-by-step explanation:

Angle 1 + Angle 2=180 degree (Linear Pair Angle)

Let,

Angle 2 = x

Angle 1 = 2 (angle 2) = 2x

Put the value of Both Angles

x+2x = 180

=3x = 180

=x = 180/3

=x = 60

Therefore;

X = 60 = Angle 2

Angle 1 = 2(60) = 120

Angle 2 = Angle 6 (Corresponding Angle)

And

Angle 6 = Angle 7 (Vertically Opposite Angle)

So,

Angle 7 = 60 degree.
