Complementary Angles And Supplementary Angles Video Lessons Examples Find the value of x if angles are supplementary angles. solution: we know that, sum of supplementary angles = 180 degrees. so, (x 25)° (3x 15)° = 180° 4x 40° = 180° 4x = 140° x = 35° the value of x is 35 degrees. example 4: the difference between the two complementary angles is 52°. find both the angles. solution:. Watch this video to learn the definitions and examples of complementary and supplementary angles, and how to use them in geometry problems.
Complementary And Supplementary Angles вђ Definition With Examples Complementary angles. two angles are complementary when they. add up to 90 degrees (a right angle ) these two angles (40° and 50°) are complementary angles, because they add up to 90°: notice that together they make a right angle. but the angles don't have to be together. these two are complementary because 27° 63° = 90°. The sum of supplementary angles is 180 degrees. therefore, the supplementary angle of 90 degrees will be. = 180°– 90°. = 90°. hence, the supplementary angle of 180 degrees is 90 degrees. example 3: find ∠hfg in the following figure. solution: ∠efh = 66 degrees. here, ∠hfg and ∠efh are complementary angles. This is because in a triangle the sum of the three angles is 180°. since one angle is 90°, the sum of the other two angles forms 90°. let’s understand the concept using some examples: determine the missing angle. solution: as we know, sum of two complementary angles = 90°, here one angle = 38°, other angle = x.
