Homework Equations
r= X +y
The Attempt at a Solution
So, first i found r by using r^2 = x^2 + y^2
and got r = √ 38
Since √ 38 cannot be factored to any lower form, i left that as the r.
Going to sin, I did op/hypotenuse
and got 6/√ 38 . However, this seems to be completely wrong as the answer is somehow 3/√ 10
I just don't see how that possible, anyone?
