CLIMBING IN YOSEMITE David and Emily are climbing El Capitan, a big cliff wall in Yosemite National Park. David is on the ground holding the rope attached to a carabiner (a rope "pulley" that is on the wall) above Emily as she climbs. When Emily stops to rest, David wonders how high she has climbed. The rope is attached to his waist, about 3 feet off the ground, and he has let out 48 feet of rope which goes up to the carabiner and then back down the wall to Emily's harness. The rope at David's waist makes a 55° angle with the ground and he is standing 20 feet away from the base of the wall. a. Assuming that the rope is taut (pulled tight), approximately how long is the rope between David and the carabiner above Emily? b. How high up the wall has Emily climbed? Describe your method.

CLIMBING IN YOSEMITE
David and Emily are climbing El Capitan, a big cliff wall in Yosemite National
Park. David is on the ground holding the rope attached to a carabiner (a rope
"pulley" that is on the wall) above Emily as she climbs. When Emily stops to rest,
David wonders how high she has climbed. The rope is attached to his waist, about 3
feet off the ground, and he has let out 48 feet of rope which goes up to the carabiner
and then back down the wall to Emily's harness. The rope at David's waist makes a
55° angle with the ground and he is standing 20 feet away from the base of the wall.
a. Assuming that the rope is taut (pulled tight), approximately how long is the rope between David and the carabiner
above Emily?
b. How high up the wall has Emily climbed? Describe your method.

Once upon a time, on a bright and sunny day, claire took a break from working at the snowcone shop. She stepped outside with her favorite book and much to her surprise, she saw a giant dinosaur! Claire is quite short. She is only 5 feet 4 inches tall and she was amazed at the giant dinosaur that towered over her. She was quite determined to find out just how tall that dinosaur was. She quickly grabbed a ruler (she is always prepared with her math tools) and discovered that her shadow was 4 feet long. She carefully measured the dinosaur's shadow. It was 50 feet long! Can you help Claire calculate the height of the dinosaur with that information? Make sure you show all your work for full credit on this assignment.
