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. (approximately). Find sin 20, cos 20, and tan 20 if sin e -- 7 and sec >0. 25 sin 20 = (Type an integer or a simplified fraction.) cos 20 = (Type an integer or a simplified fraction.) tan 20 = (Type an integer or a simplified fraction.)
