Question

Find sin q if q is an angle in standard position and the point with coordinates (4, 3) lies on the terminal side of the angle.

I don't understand what I'm suppose to be doing here.

Answer 1

Let’s say we have a starting point (0,0), the point (4,3) are distance apart at 90 degrees, hence the hypotenuse to those two distance will be 5. Therefore sin q = 4/5.
