In a ` A B C ,` if `/_A=120^0a n d\ A B=A Cdot` Find `/_B\ a n d\ /_C`

Text Solution

Verified by Experts

Given: `AB=AC`
`=>∠B=∠C` [Angles opposite to equal sides are equal]
Sum of angles in a triangle`=180°`
`∠A+∠B+∠C=180°`
`=>∠A+∠B+∠B=180°`
`=>120°+2∠B=180°`
`2∠B=180°-120° =60°`
`=>∠B=30°`
`therefore ∠B=∠C=30°`
