Two angles in a triangle are equal, and their sum is equal to the third triangle. what are the measurements of the three interior angles?

First, we can represent each of the two equal angles with x. Therefore, since the sum of these two angles equals the last angle, the last angle would be x+x or 2x. Then, since we know the angles in a triangle add to 180°, we can write out a formula and solve for x: x+x+2x=180. First, you need to combine like terms to get 4x=180. Then, you need to divide both sides by 4 to get x=45. Since we know two of our angles are equal to x, then two of our angles are equal to 45°. Then, since the last angle is equal to 2x, it must equal 90° (45*2).

I hope this helps.
