Question

Find the measure of an angle whose measure is 18 degrees less than one-half of the measure of its complement.

If x represents the measure of the angle, then which of the following expressions would equal x?

90 - (0.5x - 18)
0.5(90 - x - 18)
0.5(90 - x) - 18

Answer 1

kansaprincess, you really need to know how to do these problems, since we can't do them for you on a test.

Answer 2

you just have to substute numbers in basically. It is very simple when you get a grasp of it.

Answer 3

So you understand that a complement is 90 degrees right?

Answer 4

Says who? Lol I do online school so yeaaaaaah, y'all have done it for me so many times..lol

Answer 10

so based on that, what expressioun would the angle's complement be.
