1.	In triangle ABC,BC=AB and angle b=80 degree then find angle a
Answer» Answer: A=50 Step-by-step EXPLANATION: AB=BC it means triangle is Isosceles triangle because its two sides are equal Hence, let angle A & angle C be x as you know the sum of all angles in triangle is 180. 2x+80=180 2x=100 x=50 angle A=x which is equal to 50

Answer»

Answer:

A=50

Step-by-step EXPLANATION:

AB=BC

it means triangle is Isosceles triangle because its two sides are equal

Hence,

let angle A & angle C be x

as you know the sum of all angles in triangle is 180.

2x+80=180

2x=100

x=50

angle A=x which is equal to 50
