Step-by-step explanation:

here is ur correct answer

Answer 2

Answer:

A=100

B=40

C=40

Step-by-step explanation:

In triangle ABC

since AB=AC

then , angle B = angle C ( angles opposite to equal sides are equal )

Given : angle B = 40

therefore anvle C = 40 ( since angle B = angle C)

In triangle ABC

A+B+C = 180 (angle sum property of triangle )

A +40+40=180

A=180-80

A=100

values of A=100,B=40,C=40
