Question 566344: <) R and <) G are complentary. if m <) R = 81. what is the measure of <) G Found 2 solutions by Tias_411, bucky:Answer by Tias_411(14) (Show Source):
You can put this solution on YOUR website! Complementary angles are two angles whose measures when added together equal 90 degrees.
.
Therefore, the measures of angles R and G total 90 degrees:
.
In equation form and using your notation this is:
.
m<)R + m<)G = 90
.
But you are told that m<)R = 81 degrees.
.
Substitute 81 for m<)R in the equation and you have:
.
81 + m<)G = 90
.
Subtract 81 from both sides of this equation and you get the answer:
.
m<)G = 90 - 81 = 9
.
The answer is:
.
m<)G = 9 degrees.
.
I hope that this helps you to understand complementary angles and how they are defined.
