Question

I neeeeeeeeeeedddddd heeeeeeeelllllllllllllllllppppppppppppp!!!!!
The measure of two complementary angles are in the ratio 1 : 9. What are the degree measures of the two angles?

Answer 1

complementary angles add up to 90 degrees

Answer 2

so, if you call one of them x, then the other one must be 90 - x

Answer 3

now use this to express the ratio 1:9 and you should be able to solve for x

Answer 4

Or you could just multiply ninety by the ratio.

Answer 5

Let one be x, another one be 9x
x+9x = 90 degrees.
10x=90 degrees.
x= 90/10 = 9 degrees.
Another one is 9x = 9x9=81 degrees.
81+9=90 degrees. There's your answer :)

Answer 6

okay thanks!!! that really helps!!
