Question

if A=70 , AB=AC in triangle ABC ,then find measure of B and C​

Answer 1

Answer:

sum of all angle of a triangle =180degree

let Ab=X. , then Ac =x

angleA + angleB + AngleC =180 degree

70 +x+x =180

2x = 180-70

x = 110/2 = 55

Answer 2

Answer:

B=55

C=55

Step-by-step explanation:

opposite sides are equal then opposite angles are also equal.

B=C

A+B+C=180

70+B+C=180

so, B =55

C=55.
