A triangle has angles measuring 2x°, x° and x°. Write an equation that can be solved to find the value of x. Give the degree measure of each angle. Show your work or explain your steps.

Answer 1

The sum of the three interior angles of a triangle is always 180

Therefore if we add the expressions representing the angles, we get the following equation:

2x + x + x = 180

4x=180

x=45

2x=90

So the angles of the triangle are 45, 45 and 90
