Question

In ABC of a triangle, B=C and A=100 degrees find B​

Answer 1

Answer:

b is 40

and c is 40

because the given triangle is isocelous triangle so

2x+100=180

2x=180-100

2x=80

x=40

mark me as brainliest

Answer 2

Step-by-step explanation:

As we know ,

∆A+B+C = 180°

given A = 100 , B = C

A+B+C = 180°

100+B+C =180°

180° - 100 = 80°

as , B = C

A + B + C = 180°

100 + 40 + 40 = 180°
