  • 15 ft
  • One day Maya and Alec decided they wanted to go to a skate park. Maya is standing 12 ft from the base of the ramp looking up Alec at 47 degrees. She wonders how high she is looking up Alec is when he is kneeling at the top of the ramp. So she uses a tangent function and finds out cos(47)= 12/x. x=17.6
  • Maya decides she wants to go to a different ramp to practice her own skating. She approaches another ramp. The ramp is 15 ft high and her angle to the ramp is 49 degrees. She tries to figure out how far away she the top of the ramp. sin(49)=15/x. x= 19.89
  • THEEND
  • Maya runs up the ramp.
  • When Maya reached the top, she looks down to the ground. She stands 5 ft higher than the top of the ramp but the distance from the base to the place she is looking at remains 19.89 ft. What is the angle she is looking down at. tan-1(19.89/20)= x.x= 44.84 degrees
