Find the measure of ∠LNM in the given figure.
A 30°
B 80°
C 70°
D 60°
Ans 1:
Class : Class 7
Option d is right answer as, angle KLO is equal to angle MLN because these are vertical opposite angles. So, we have to angles of a triangle. Take angle LMN equal to x. Then form the equation - x+70+50=180 = x+120=180
x=180-120=x=60
