Answer 1

Answer:

may be my answer help's you

Step-by-step explanation:

Given, AB = AC, ∠B=70

∠B=∠C=70

∘

(Isosceles triangle property)

Sum of angles,

∠A+∠B+∠C=180

∠A+70+70=180

∠A=40∘

Answer 2

Answer:

ABC =180

BAC=70

AB=AC

A+B+C = 180

70+B+C= 180

B + C = 180 - 70

B + C =110

B=55

C=55

B Angel is 55°
