The vertex angle of an isosceles triangle is 10 less than three times the base angles. Find each angle.

Answer: (2x-10)+(2x-10)+x = 180 Combine the like-terms.

5x-20 = 180 Add 20 to bothe sides.

5x = 200 Divide both sides by 5.

x = 40 degrees.

2x-10 = 70 degrees.

The three angles are:

Vertex angle = 40 degrees.

The base angles are each 70 degree.
