Complementary angles total 90 degrees so smaller is 90/5 ie 18 and larger 72.
complementary angles sum to 90o so 60o is your answer.
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
acute
A rectangle has four angles inside it. Each of them is a right angle (measures 90 degrees).
A straight angle is an angle that measures 180 degrees and is drawn as a straight line. A straight angle is composed of two right angles whose measures are 90 degrees each.

Complements are defined for angles, not trigonometric ratios of angles.
63
The missing angle measure is 100 degrees.
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
the answer is 22,97
23 degrees and 67 degrees
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
A 60 degree angle
A pair of complementary angles are two angles which add up to equal 90 degrees. In this instance, the complementary angle to 65 degrees is equal to 90 - 65 = 25 degrees.
acute
Alternate angles are equal and so angle b is also 105 degrees
