Construction 1: For this problem, use pencil and paper or a computer graphing program such as The Geometers Sketchpad. Construct a right triangle with one horizontal leg 8 cm long and an acute angle of 35 with its vertex at one end of the 8-cm leg. Measure the hypotenuse and the other leg. Use these measurements to calculate the values of sin 35 and cos 35 from the definitions of sine and cosine. How well do the answers agree with the values you get directly by calculator? While keeping the angle equal to 35, increase the sides of the right triangle. Calculate the values of sin 35 and cos 35 in the new triangle. What do you find?
