#### Storyboard Text

• Scene One
• Oh no! There is a cat stuck ﻿up in that tree!
• ﻿Scene Two
• Let's see how it can come down safely.﻿The tree is about 75 feet high﻿...
• ﻿Scene Three
• How will ﻿we know how far to set up the ladder to the tree?
• We need a ladder that is about 100 feet to reach the top.﻿
• ﻿The lady spots a pet cat stuck high in the tree
• ﻿Scene Four
• Well we can use the law of cosines! the angle of elevation is about 32 degrees.﻿
• first we do a^2 = 75^2 + 100^2  - 2(75)(100)(cos32) on the calculator. ﻿a^2 then equals 2904.28, we square root that to equal 53.89.
• The man ﻿overhears and wants to help figure out a way to rescue it.
• ﻿Scene Five
• How do we solve that?﻿
• ﻿The guy states what they need. The lady wants to know how far to place the ladder to connect it to the tree.
• ﻿Scene Six
• So approximately we have to set the ladder 54 feet away from the tree? ﻿
• The guy tells ﻿her they can use the law of cosines to figure that out.
• ﻿the lady asks how to solve it and then man proceeds to explain how to do it on the calculator.
• they then figured out how far the ladder needed to be to rescue the cat﻿
