Question

in triangle abc if AB=AC and <A = 50° then the value of <B = ?​

Answer 1

Step-by-step explanation:

I've already tagged the solution as a picture

but for better understanding you can refer the below solution

from the diagram

angleB=angleC

so A+B+C=180

50°+ B+B=180°

2B=130°

B=65°

similarly

C=65°

Answer 2

Answer:

<B = 80°

Step-by-step explanation:

Given AB= AC and <A = 50°

we have to find <B

As <A = 50° and

<C = 50° ( given AB = AC)

therefore,

<A+<B+<C = 180°

50°+ <B+ 50° = 180°

100° + <B = 180°

<B. = 180°-100°

<B. = 80°

So <B = 180°
