Question

find X , y and z from this figure.

Answer 1

angle x=53°(alt. angle)
angle x + angle Y=127°(exterior angle is equal to sum of the opposite two interior angle)
therefore, angle Y =127°-53°=74°
now in ∆,angle x +angle Y+ angle z=180°
therefore,angle z=180-(74°+53°)
=53° ANS

Answer 2

y=127-53
 =74
z + (y+53)=180 (co - interior angle)
Z=53
x=53 ( sum of interior angles of triangle)
