Final answer:
The first two angles in the triangle are 36 degrees, while the third angle is 108 degrees.
Step-by-step explanation:
Let's denote the first angle as x. Since the two angles are the same size, the other angle will also be x. The third angle is 3 times as large as the first angle, so it will be 3x.
We know that the sum of the angles in a triangle is 180 degrees.
Therefore, x + x + 3x = 180.
Combining like terms, we can simplify the equation to 5x = 180.
Dividing both sides by 5, we find that x = 36.
Hence, the angles in the triangle are: x = 36 degrees, x = 36 degrees, and 3x = 3 * 36 = 108 degrees.
