Answer 1

angle b 80 degree

angle c 120 degree

Answer 2

Other two angles are of equal measures so angle A is 40°, angle B= angle A

Angle A + angle B +angle C=180°______Sum of all all angles of a triangle

angle A+ angle B+ angleB =180° _____angle B= angle C

40°+2angleB =180°

angle B=180°-40°/2

angle B =70°

Therefore angle C=angleB=70°

The measures of the angles are 40° ,70° and 70°
