Question

In the figure given below, find the value of angle x if line L is parallel to M

Answer 1

Answer:

if line L is parallel to M

then, angle 1 + angle 60°= 180

( co interior angles)

so angle 1 = 180 - 60

angle 1 = 120°

now by vertical opposite angles

angle 1 = angle 2

hence angle 2= 120 °

now angle sum property in triangle acb

25°+120°+x= 180°

x= 180°-145

x= 35°

hence the value of x= 35°
