#### Storyboard Text

• Ike saw a black cat in a tree and proceeded to take heroic action to attempt to save the unlucky animal.
• The cat jumped down itself, and now Ike got ﻿himself stuck! He wanted to get down, but he needed to know how high up he was. Good thing Ike has prepared himself for this situation. He has studied the rock. He new that the tree was 16.5 feet away from a rock and that the angle of elevation of the rock is 43°. ﻿So he thought of the equation: tan43°=﻿﻿x / 16.5. So he typed in his phone: 16.5﻿(tan43°﻿﻿). This let him know that he was about 15.4 feet from the ground. This was too high for him to jump.
• x﻿
• ﻿16.5 feet
• 43°﻿
• Ike began to get scared, but then he noticed a 6ft﻿ stack of tires to the left of the tree. Again, Ike was prepared. He had measured the angle of elevation from the tires to the top of the tree for a recent math project. The angle was 80°.﻿And now that he knew how high he was, he subtracted the height of the tires and found that the tires were 9.4 feet below him. He needed to find the distance between him and the tires. So he used the equation: sin80°﻿= 9.4 / x.
• ﻿So he typed in his phone: 9.4 / sin80°﻿. This let him know that he was about 9.6 feet from the tires. He was ok with this height, and leaped.
• ﻿6 ft
• x﻿
• ﻿80°
• ﻿9.4 feet
• ﻿This was a major miscalculation, causing Ike to break his ankle. It turns out that black cats really are unlucky.
• Ike used the equation cos-1(40 / 85). This helped him find that the hill declined at a 61.9°﻿ angle. This was barely not too steep for Ike to walk down. So he took the risk and went to his car.
• ﻿In order to get to his car, Ike had to walk down a steep hill. A sign said that the hill was 40 ft high and the sign is 85 feet from the bottom. Ike needed to know the angle of depression.
• 85 feet﻿
• x°﻿
• ﻿40 feet
• THE END
• ﻿Ike arrived at the hospital and not only was diagnosed with a broken ankle, but also now had a terrible phobia of cats, trees, and tires.
