A ski resort is located on a mountain that is 10,000 feet tall. To get to the top of the mountain you have to
take a ski lift that makes a 20 degree angle with the ground. You will need to know that cos(20°)=0.94
sin(20°)=0.34 to answer these questions without a calculator. Leave your answers as fractions.
