Question

1. In ABC, AB = BC and B = 3 A, find A, B, C.​

Answer 1

Step-by-step explanation:

We can see that ∠A = ∠C [∵AB=AC]

∠A +∠C + ∠B = 180

∘

{∵ sum of all the angles of triangle is 180

o

}

so, 2∠C = 180

∘

- 64

∘

= 116

∘

(since ∠A = ∠C)

⇒∠C =

2

116

∘

=58

∘

⇒∠A = 58

∘

and ∠C = 58

∘

⇒∠C = 58
