value of a and b is 50° and 70° respectively

Hope it will help you.

Answer 2

Answer:

L a=50°,L b=70°

Step-by-step explanation:

La=50°(corresponding angle of 50° )

60°+La+Lb=180°(angle sum property)

60°+50°+Lb=180°

Lb=180°-(60°+50°)=180°-110°=70°

corresponding angles are equal

angle sum property. sum of all angles of triangle measure 180°
