Complementary Angles:If the sum of two angles is 90 ⁰, then those two angles are called as complementary angles.Example:30° and 60° are complementary angles.Because,30° + 60° = 90°Clearly, 30° is the complement of 60° and 60° is the complement of 30°.Supplementary Angles:If the sum of two angles is 180 ⁰, then those two angles are called as supplementary angles.Example:120° and 60° are supplementary angles.Because,120° + 60° = 180°Clearly, 120° is the supplement of 60° and 60° is the supplement of 120°. Practice QuestionsQuestion 1:The measure of an angle is 41°. What is the measure of a complementary angle?Answer:Let x be the measure of the required complementary angle.Because x and 41° are complementary angles,x + 41° = 90°Subtract 41° from each side.x = 49°So, the measure of the complementary angle is 49°.Question 2:The measure of an angle is 62°.
What is the measure of a complementary angle?Answer:Let x be the measure of the required complementary angle.Because x and 62° are complementary angles,x + 62° = 90°Subtract 62° from each side.x = 28°So, the measure of the complementary angle is 28°.Question 3:The measure of an angle is 108°. Toca boo trailer. What is the measure of a supplementary angle?Answer:Let x be the measure of the required supplementary angle.Because x and 108° are supplementary angles,x + 108° = 180°Subtract 108° from each side.x = 72°So, the measure of the supplementary angle is 72°.Question 4:The measure of an angle is 89°. What is the measure of a supplementary angle?Answer:Let x be the measure of the required supplementary angle.Because x and 41° are supplementary angles,x + 89° = 180°Subtract 89° from each side.x = 91°So, the measure of the supplementary angle is 91°.Question 5:Two angles are complementary. If one of the angles is double the other angle, find the two angles.Answer:Let x be one of the angles.Then the other angle is 2x.Because x and 2x are complementary angles, we havex + 2x = 90°3x = 90Divide each side by 3.x = 30And,2x = 2(30) = 60So, the two angles are 30° and 60°.Question 6:Two angles are complementary.

If one angle is two times the sum of other angle and 3, find the two angles.Answer:Let x and y be the two angles which are complementary.So, we havex + y = 90° - (1)Given: One angle is two times the sum of other angle and 3.Then,x = 2(y + 3)x = 2y + 6 -(2)Now, substitute (2y + 6) for x in (1).(1)- 2y + 6 + y = 903y + 6 = 90Subtract 6 from each side.3y = 84Divide each side by 3.y = 28Substitute 28 for y in (2).(2)- x = 2(28) + 6x = 56 + 6x = 62So, the two angles are 62° and 28°.Question 7:Find the value of x.
