Question

in an isosceles triangle the base angles are equal .the vertex angle is 3 times the base angle .find each angle of the traingle​

Answer 1

Answer:

answer is 70 degree

It is given that the base angles of an isosceles triangle are equal and the vertex angle of an isosceles triangle is 400 . We know that the sum of three angles of a triangle is 180 degrees. x = 70. Hence the base angle of an isosceles triangle is 70 degree.
