# Thread: Geometry, angles and funtions help.

Write a function f that maps the measure x (in degrees) of an angle to the measure of its complement (in degrees). Describe the domain of the function.

$f(x)=90-(x \mod~ 90)$ Now you explain that answer.

Hi iepicfellow,

I notice you are a "newbie". As a volunteer helper on this site, I don't respond to questions like yours (although I have, in a way, here) because:
1. You didn't say please
2. You didn't show any attempt at doing the question yourself
That's all.

Would you like fries with that?
