Question

B A In this figure, AB || CD and m/3 120 What is m/6? D Enter your answer in the box.

Answer 1

Step-by-step explanation

AB is parallel to CD and then, there's a transversal that cuts across the two lines. We are given that Angle 3 = 120°

But we ca see from the figure that Angle 3 and Angle 2 lie on the same straight line.

And we know that the sum of angle on a straight line is 180°.

Hence,

(Angle 3) + (Angle 2) = 180°

120° + Angle 2 = 180°

Angle 2 = 180° - 120°

Angle 2 = 60°

Then again, we can see that AAA
