Answer:

Draw a right triangle with a 20 degree acute angle and with a hypotenuse of one meter. Then take your meter stick and measure the leg next to the 20 degree angle. You should get a length of 98.9 cm. Dividing that by 100 cm which is the hypotenuse, you will get 0.989 approximately, which is = cos 20 deg.
