Factor is the numbers that divides another number or expression without the remainder. For example, 3 and 6 are factors of 12 because 12÷ 3=4 and 12÷6=2.
All you need is use sin cos tan for doing this
sin (angle)= O/H
cos (angle)= A/H
tan (angle)= O/A
216 divided by 3 is 72 so making the answer
1/72
