Answer 1

Answer:

ANGLE -2 AND ANGLE -3 = 70⁰

Step-by-step explanation:

given angle1 : 40⁰, angle2 = angle3 = x

sum of all angles in a triangle = angle1+angle2+angle3 = 180⁰

                               40⁰+2x = 180⁰

                                     2x = 140⁰

                                        x = 70⁰
