You are watching: What is the complement of 47
Here is a look at at 2 of the relationships.Supplementary angles room two angles that have actually a sum of 180°.
Complementary angles are two angle that have a amount of 90°.
There is one easy way to shot and remember these making use of the very first letters of every word.The S in supplementary have the right to be supplied to form the 8 in 180.
The C in complementary deserve to be used to form the 9 in 90.
If we recognize that a collection of angles form one the these one-of-a-kind relationships, we have the right to determine the measure of the various other angle.Example #1: 43°To determine the supplement, subtract the given angle indigenous 180.180 - 43 = 137°The supplement of 43° is 137°.To determine the complement, subtract the given angle from 90.90 - 43 = 47°The enhance of 43° is 47°.Example #2: 61°180 - 61 = 119°The supplement of 61° is 119°. 90 - 61 = 29°The match of 61° is 29°.Example #3: 127°180 - 127 = 53°The complement of 127° is 53°.127° is already greater 보다 90°. Therefore, over there is no complement.Example #4: recognize the missing angle.
Notice the the two angles for a ideal angle when together. This method that the angles are complementary and have a sum of 90°.
The absent angle measures 28 degrees.Example #5: recognize the absent angle.
These 2 angles kind a right line. Directly lines measure 180°. That method that these two angles are supplementary.

The missing angle measures 103 degrees.Let"s ReviewComplementary angles kind a best angle (L shape) and have a amount of 90 degrees.Supplementary angles form a straight line and also have a sum of 180 degrees.If the partnership is given, you can subtract the offered angle from the amount to recognize the measure of the absent angle.
