Please help so I don’t fail this class What is the measure of the reference angle for a -287° angle

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

you need to give us more information since we can't answer
