"An angle has a measure three times that of its complement. What is the measure of the angle?"

Complementary angles add up to 90 degrees. If x is the complement and 3x is the angle, and you added them to have 4x, then you'd have 4x=90, right? That would then mean x=22.5 and 3x=67.5. They would then equal 90 degrees. What I am wondering is if I did this right, and if there can actually be an actual 67.5 degree angle. Anyone have any advice/solutions?

You did it right.
There is no reason an angle can not be measured in fractions of a degree.
