In an isosceles triangle if the vertex angle is twice the sum of the base angles, calculate the angles of the triangle

In an isosceles triangle, if the vertex angle is twice the sum of the base angles, then the measure of vertex angle of the triangle is (a) 100^0 (b) 120^0 (c) 110^0 (d) 130^0

In an isosceles triangle,if the vertex angle is twice the sum of the base angles,then the measure of vertex angle of the triangle is 100^(0) (b) 120^(0) (c) 110^(0) (d) 130^(0)

In an isosceles triangle, if the vertex angle is equal to the sum of the base angles, then the measure vertex angles of the triangles is

In an isosceles triangle,the vertical angle is 15 more than each of its base angles,Find all the angles of the triangle.

In an isosceles triangle, if the unequal angle is twice the sum of the equal angles, then each equal angle is

The vertical angle of an isosceles triangle is twice the sum if its base angles. Find each angle of the triangle.

Set up an equation in the following cases: In an isosceles triangle, the vertex angle is twice either base angle. (Let the base angle be b in degrees. Remember that the sum of angles of a triangle is 180 degrees).

In an Isosceles triangle the base angles are equal and the vertex angle is twice of each base angle. Find the measures of the angles of the triangle.
