How do I find the measurement of an angle of a triangle if I know what the other two angles are. For example, I know the first is 90 degress, the second angle is 30 degress, but I need to know what the third angle is.

As for your earlier question about the corner cabinet, I need a picture to understand.

Height from the floor to the counter is 30 or is it the altitude of the triangle the counter shape is? Hypotenuse of what triangle? perimeter around the counter or the cabinet face where the door is or what?

I did not post because some teacher might think I answered and skip over the question.
