(1) x=40° and y=35°. (Alternative angles)
So, x+y=75°
(2) Angle CAB + Angle CBA + Angle ACB= 180°
Angle ACB=100°
So Angle CAB + Angle CBA= 180°-100° =80°
Now, Angle CAB= 2x
and Angle CBA=2y
So, 2x+2y=80°
2(x+y)=80°
x+y=40°
So, x+y=75°
(2) Angle CAB + Angle CBA + Angle ACB= 180°
Angle ACB=100°
So Angle CAB + Angle CBA= 180°-100° =80°
Now, Angle CAB= 2x
and Angle CBA=2y
So, 2x+2y=80°
2(x+y)=80°
x+y=40°
