Use a Compass to Sketch a Quarter of a Circle

question 221

Multiple Choice

Use a compass to sketch a quarter of a circle of radius 10 centimeters.Using a protractor, construct an angle of in standard position (see figure) .Drop a perpendicular line from the point of intersection of the terminal side of the angle and the arc of the circle.By actual measurement, calculate the coordinates of the point of intersection and use these measurements to approximate the six trigonometric functions of a angle.(Round your answer to two decimal places.)
