Answer 1

Answer:

I think so your question is wrong because u gave angle A as 120° but what is the value of AB - AC.

Please tell.

Send the proper question, then only I can answer.

Sorry for not answering u.

Answer 2

Answer:

I think u meant it as AB=AC. If so, here's the answer.

Step-by-step explanation:

Given, a°=120°

AB=AC

Since, AB=AC, Triangle ABC is an isosceles triangle.

So, b°=c° .....(1)

Let b° be x

a°+b°+c°=180° (angle sum property)

120°+b°+c°=180°

120°+x+x=180° ......(from 1)

120°+2x=180°

2x=60°

x=30°

Therefore,

b°=30°

c°=30°
