Answer:
Step-by-step explanation:
Let the first angle be . Then, the second angle is and the third angle is .
We know that the sum of the angles in a triangle will always be . So, we want to solve the equation for x: .
Combining like terms on the left side gives .
Subtracting from both sides gives .
Dividing both sides by gives .
So, the first angle is .
The second angle is , so the second angle is .
The third angle is , so the third angle is .
So, the angles are and we're done!
The check that these angles work is left as an exercise to the reader.
