Question

in triangle abc if angle A- angle b is equal to 60 degrees and Angle B-angle C is equal to 18 degrees then the measure of Angle B is​

Answer 1

Measure of all three angles of a triangle is 180°

angle A + angle B + angle C = 180°

60° + angle B + 18° = 180°

78° + angle B = 180°

anble B = 108° - 78°

=102°

angle B = 102°
