Question 995584: find the measures of two complementary angles if one angle is 18 degrees more than 3 times another angle Answer by Timnewman(323) (Show Source):
You can put this solution on YOUR website! let a and b be the comp angles.
From your question,
a+b=90---(1)(complementary angles sum up to 90)
a=3b+18---(2)
put 2 in 1
3b+18+b=90
4b=90-18
4b=72
b=18
put b=18 in 2
a=3(18)+18
a=72
The measure of the angles are 18degree and 72degree
