Question

Q8. In AABC, if AB = BC and 2B = 70 then A=?

70°
110°
550
130
​

Answer 1

Answer:

It's easy

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
