While you're at the top of the tower (50 meters tall), you see an ant walking along the edge of the building. If the ant were to walk straight down the side of the tower (86 degree angle) until it reached the ground, how far would the ant travel? Which trigonometric ratio would you use to find this distance? Use the ratio to find the measurement. (4 points: 1 point for the method, 2 points for shown work, 1 point for the answer)
