Ok, a right triangle has one 90 degree angle, and two other angles. Both the other angles are acute (less than 90 degrees). And the angles of a triangle add up to 180 degrees. So,
Let X = the unknown acute angle measure, then:
90 + 68 + X = 180
Combine like terms, and then solve for X. I'll leave that part for you to do, ok?
