The measures of the angles of a triangle are represented by 2x+15, x+20, and 3x+25. find the measures of the triangles

55°, 40° and 85°

Step-by-step explanation:

For a given triangle, the sum of its interior angles is equal to 180°.

Here, the interior angles are and .

∴

Now, plug in 20 for x and evaluate each angle.

So, °

°

°

Therefore, the measures of the angles of the triangles are 55°, 40° and 85°.
