Question

triangle ABC if angle A is equal to 80 degree and a b is equal to AC then find the value of Angle B​

Answer 1

Answer:

50

Step-by-step explanation:

ABC is an isoceles triangle

so, angle b = angle c

2angle b = 180- 80

angle b = angle c = 50 degrees

Answer 2

Answer:

Since it is an isosceles triangle,

angle B = angle C

So,

80+x+x=180

2x=100

x=50

Angle B=50 degrees
