Remember, supplementary angles add to 180 degrees. So this means that
Start with the given equation.
Combine like terms on the left side.
Add to both sides.
Combine like terms on the right side.
Divide both sides by to isolate .
Reduce.
-------------------------------
Go back to the first angle
Plug in
Multiply
Reduce
Subtract
So the first angle is 58 degrees
----------------------------------------
Go back to the second angle
Plug in
Multiply
Reduce
So the second angle is 122 degrees
==================================================
Answer:
So the two angles are 58 and 122 degrees
