Find the unknown angles- Share with your friends Share 1 Amit Shukla answered this Dear Student, cosidering lines l and m are parallel and another l is acting as a tranversal.d+60°=180° (linear pair)d=120°and,b=60° (vertically opp. angles)d=c=120° (vertically opp. angles)c=g=120° (alternate int. angles)and g=f=120° (vertically opp. angles)e=60° (alternate int. angles)and,e=h=60° (vertically opp. angles) Hope, you will find this answer helpful. 0 View Full Answer Rohan Dey answered this angle b=60[vertically opposite] ,b+c =1800 so angle c =1800_600=1200, angle d = 1200[vertically opp to anglec.] angle g= angleb [alternate angles to angle c, angle e is 600[alternate to angle 600] angle h= 600[corresponding to 600] angle f = 1200 [corresponding to angle c] -1
