Question

In triangle ABC, if AB=BC and ∠B = 70, ∠C will be: * a) 70 b) 110 c) 55 d) 130 ?​

Answer 1

Answer:

Step-by-step explanation:

since, AB=BC

angle A = angle C

let angle A = x

so, angle C is also equal to x

angle A + angle B + angle C = 180 degree

2x + 70 = 180 degree

x = (180-70)/2

x = 55 degree
