Question

find the measure of X Y Z in the figure where l//BC

Answer 1

x= 180 - 75-45=180-120=60..(since it is a linear angle)
angle Y = 75 ( alternate interior angle where BC//l)

and angle z = 45 degree (alternate interior angle)
THANKYOU....

Answer 2

Answer:

<×=180°-(75+45)=60°;<y=75°;z=45°
