Question

ABC is a triangle with AB = AC, if angle B = 65 degree, then measure of angle C is
​

Answer 1

Answer:

57.5°

Step-by-step explanation:

Total measure of all angles of triangle is 180°

AB=AC

B=65°

By the formula

180° = 65 + 2x

= 2x = 180- 65

= 2x = 115

= x = 57.5°

Answer 2

Answer:

angle C = 65 °

Step-by-step explanation:

In triangle ABC,

AB=AC............given

AB=AC............given i.e ABC is isosceles triangle

angle B = 65°

- angle B = angle C

according to isosceles triangle theorem

Therefore,

angle C = 65°
