Plz solve it and help me for it​

Given:

Base angle of an isosceles triangle is 15 degrees more than its vertical angle.

To find:

The measure of each angle of the triangle.

Solution:

Let x be the vertical angle. Then,

One base angle = x+15 degrees

We know that base angles of an isosceles triangle are equal.

Another base angle = x+15 degrees

Now, the sum of all angles of a triangle is 180 degrees by the angle sum property.

         (Angle sum property)

Divide both sides by 3.

The measure of base angles is

Therefore, the measure of angles are 50°, 65° and 65°.
