Answer: three angles of the triangle are 24 degrees, 84 degrees, and 72 degrees.
Explanation:
Let's call the first angle x.
Then the second angle is x + 60.
And the third angle is 3x.
We know that the sum of the angles in a triangle is always 180 degrees.
We can use this information to set up the following equation:
x + x + 60 + 3x = 180
5x + 60 = 180
5x = 120
x = 24
So the first angle is 24 degrees.
The second angle is 24 + 60 = 84 degrees.
And the third angle is 3x = 3 * 24 = 72 degrees.
Therefore, the three angles of the triangle are 24 degrees, 84 degrees, and 72 degrees.
