Question

In the given fig. l parallel to m find value of X ​

Answer 1

Answer:

42°

Step-by-step explanation:

let the triangle be ∆ABC, where

A=40°; B=y°;C=x°

Since, angleA + angle B + angle C=180°(angle sum property)

Therefore, 40+x+y=180

y=98°(vertically opposite angle)

40+98+x=180

138+x=180

x=180-138

=42°
