Answer:

<h2>50°, 60°, 70° (the second answer)</h2>

Step-by-step explanation:

The sum of the angles in a triangle = 180°

We can use the equation:

2x + 80 + 25 - 5x + 6x + 90 = 180

Combine like-terms:

2x + 6x - 5x = 3x

80 + 25 + 90 = 195

195 + 3x = 180

Subtract 195 from both sides:

3x = -15

Divide both sides by -3 to isolate x:

x = -5

Now that you've solved for x, you can replace x with -5 in the equation for each angle.

2(-5) + 80 = 70°

6(-5) + 90 = 60°

25 - 5(-5) = 50°
