Question

triangle ABC is isosceles death is equal to BC if Angle B is twice the measure of angle A find the measure of all angles of the triangle ​

Answer 1

Step-by-step explanation:

let the angle A be x

therefore angle b =2x

since triangle is isosceles triangle

therefore angle A = angle B

therefore X+X+2X=180

therefore X = 180/4

X=45 degree

2X = 2x45 = 90 degree

therefore angle A = angle C =45 degree,

Angle B = 90 degree
