Question

Q7. In the figure AB=AC, Find angle A.​

Answer 1

Step-by-step explanation:

angle 120°+ acb =180 linear pairs

angle acb = 60°

angle ABC = ACB = 60°

angle ABC + angle ACB + angle A = 180°

60° +60° + angle A = 180°

angle A = 180 - 120

angle A = 60°

Answer 2

Answer:

60

Step-by-step explanation:

because ab=ac and the half revolution creates 180 degree angle when we minus this from 120 then we found 60 .

and has two side are equal angle also equal.

angle B is equal to angle c so the

total sum of a triangle angle is 180.

we give 60
