please explain the steps to the answer

Use the foliowing gure. When we are working with a circle whose radius is not 1, we use X = r co5[6} and y = r sin(|9) to nd the coordinates of the endpoint of an arc. We can rewrite these formulas as i = cos(6] and L = sin(9} by dividing by r. r r For the indicated point, do the following. 3 (a) Estima e the (x, y) coordinates For the indicated point. (x.y)z( )
