- A Trip to the ZooBy: Dipra 10F
- Once upon a time, a girl travels to the zoo and she sees their tropical exhibit first. She wonders how high up a parrot is on a palm tree. She knows the angle of inclination between the tree and the ground is 20 degrees. The inclined length of the branch up to the parrot is 5 meters. To calculate the height, she uses sine. She calculates Sin(20)x 5=height. The height of the tree is around 1.7 meters

- The girl's second stop is to the petting zoo where she sees farm animals playing in their pen. She wants to find the distance between a baby duck and a little sheep. The distance from the feet of the duck to the top of the sheep is 2 meters and the angle of inclination is 40 degrees. So, she uses cosine to calculate the X value. Cos(40)=X/2------> Cos(40) x 2=XThe sheep is around 1.5 meters away from the duckClick To EditOnce upon a time, a girl travels to the zoo. Her first stop is at the petting zoo where she sees farm animals playing in their pen. She wonders what the angle is from the pen to the ground. She measures the distance from the pen to the nearest sheep and it is 30 inches. The sheep is 46 inches tall. The girl uses trig and calculates tan-1(30/46)=33.1, so the angle is around 33 degrees.

- The zoo is on the coast and near to the ocean. The girl spots a seal in the distance while she is walking to the next zoo exhibit. The lighthouse is 35 meters tall and the angle of inclination between the seal and lighthouse is 22 degrees. The girl wants to know how far the seal is from the top of the lighthouse, so she uses sine to find out. Sin(22)=35/X ----> 35/Sin(22)=XThe top of the lighthouse is 93.4 meters away from the seal.

- The zoo offers hot air balloon rides to have an overhead view of all the animals. The balloon flies to a height of 30 ft. The girl estimates that it is horizontally 12 ft away from her. To calculate the angle of inclination, she uses inverse tan. Tan-1(30/12) so the angle is around 68 degrees.
