Question

hi friend please tell the answer to 1 st question

Answer 1

angle A=35°(V. O. A)

angle ACB=180°-100(LINEAR PAIR)

=80°

BY ANGLE SUM PROPERTY OF TRIANGLE angle A+B+C=180°

35°+80°+angle ABC=180°

angle abc=180°-115°

=65°

Answer 2

Answer:

angle A= 35°(Vertically opposite angles)

angle C=180-100=80°

angle B=180-115=65°
