Answer 1

Answer:

70 degrees

Step-by-step explanation:

Angle ACB = 60°

Angle ABC= 180-(60+50) = 70°

Answer 2

Answer:

70°

Step-by-step explanation:

Sum of all the interior angles of a triangle= 180°

Angle A= 50°

Angle C= 180°-120°= 60°

Angle B= 180°-(50°+60°)

             = 180°-110°

             = 70°
