To find the measure of the angles in the triangle, set up an equation using the fact that the sum of the angles in a triangle is always 180 degrees.

Let's denote the three angles of the triangle as A, B, and C.

We are given:

A = 2x - 7 degrees

B = x + 25 degrees

C = 3x + 12 degrees

Since the sum of the angles in a triangle is always 180 degrees, we have the equation: A + B + C = 180

Substituting the given angle measures, we get: (2x - 7) + (x + 25) + (3x + 12) = 180

Now, solve for x and find the value of each angle.
