3. An angle is drawn in standard position. Write your answers in exact form. (3.1) (2 points) The angle 0 intersects the circle as shown below. Determine the radius of the circle. Y (5,53) (3.2) (3 points) The angle 0 is the same as in 3.1, but the radius has changed. If the point where intersects the circle has y- coordinate 7, find the radius r and leg w. Y Work: Radius: r x X (3.3) (3 points) Determine tan(0) by using 0 in 3.1 or 3.2. (3.4) (2 points) Find the equation of the line in y = mxb form that lies on top of the radius in both 3.1 and 3.2. Leg w: Radius r: |tan(0) = Equation:
