In a right triangle, there are three angles, a right angle and two acute angles. In every traingle, the sum of the measures of the angles is 180 degrees. Let's call the acute angles and
.
The problem also says that one angle is twice the difference of the other angle and 12. That would look like this:
Now we have two equations. If we simplify them, we get these:
Now you can substitute in the first equation for
in the second equation
Add to both sides of the equation
Add to both sides
Divide both sides by 3
Now, you can substitute for
in the first equation and simplify.
