Question

In the given figure, if l, m and n are parallel lines andΔ1=60°,then find Δ2.​

Answer 1

Step-by-step explanation:

angle 1 would be equal to angle 3 cause they are corresponding angles.

So angle 3=60°

Now Angle 3+4=180°

60+angle 4=180

Angle 4= 120°

Angle 4=Angle 2

Alternate Interior Angles

So angle 2 is of 120°

Hope it helps buddy..

Stay blessed ❤️✨❤️

Answer 2

Answer:

Answer is 120°

Step-by-step explanation:

Angle 1 = Angle 3 ( Corresponding Angles ) =60°

Angle 3 + Angle 4 = 180 (Linear Pair )

Angle 4 = 180-60 =120°

Angle 4 = Angle 2 ( Alternate Interior Angles )
