Webx + y + 90o = 180o. x + y = 180o − 90o. x + y = 90o. That is, the sum of the two acute angles in a right triangle is equal to 90o. If we know one of these angles, we can easily substitute that value and find the missing one. For example, if one of the angles in a right triangle is 25o, the other acute angle is given by: 25o + y = 90o.
