Question

in triangle abc angle b is equal to angle C and Angle A is equal to 100 find Angle B​

Answer 1

Answer:

let angle c and b =x

and given angle b= 100

so a+b+c=180

100+x+x=180

100+2x. =180

2x. =80

x. =40

so angle b and c = 40 ans

please mark me as brain list

Answer 2

Answer:

In a triangle,

Sum of all angles = 180

Since, angle A = 100

angle B = angle C

So, angle A or B = (180-100)/2

= 80/2

= 40
