90 degrees
The sum of the angles of a triangle is 180 degrees. A right angle is 90 degrees. So the sum of the remaining two acute angles of a right triangle is 90 degrees.
The sum of an angle and its complement is 90 degrees. So the unknown angle must be 90 - 75 = 15 degrees.
Exactly 90 degrees.

90+90+90+90
Yes. A triangle has 180 degrees total, so if one of them is a right angle, which means it is 90 degrees, the sum of the remaining two angles is 180-90=90 degrees.
Angle and its complement have a sum of 90 degrees: A+C = 90 Angle plus five times its complement is 298 degrees: A+5C = 298 Subtract first equation from the second: 4C = 208 C = 52 So, the complement is 52 degrees and the angle is 38 degrees
45 degrees and 45 degrees.
