Given - AB=AC
            ∠ B=700
To Find - ∠A
Solution - AB=AC
                ∠C=∠B (Isosceles triangle property)
            Let ∠​B=∠C=x
           ∠A + ∠B + ∠C = 1800 (Angle sum property)
           ∠A + 700 + x = 1800
           ∠A + 700 + 700 = 1800
           ∠A + 1400  = 1800
             ∠​A = 1800 - 1400
         ∠A = 400
