Question

in figure m parallel n and the angle 1=60degree .Find Angle 6 and Angle 7​

Answer 1

From the figure :

I , m and n are parallel lines .

< 1 = 60 ° .

< 1 + < 4 = 180 °

/ * Sum of exterior angles same side of the transversal are supplementary * /

= > 60 ° + < 4 = 180 °

= > < 4 = 180 ° -60 °

= > < 4 = 120 °

Now ,

< 2 = < 4 / * Alternate angles * /

= > < 2 = 120 °

Therefore , < 2 = 120 °
