Answer 1

Answer:

If the unnamed angle is 100°and L||M then angle d = 100° by vertically opposite angle.

100° = angle b 【by alternate angle 】

Angle b + unnamed angle =180° 【Because l is a line】

180°-100°=80°

Unnamed angle1 =80°

Unnamed angle 1=Angle a=80°【Bycorresponding angle】

Angle d=100°【By corresponding angle】
