#### Storyboard Text

• 8﻿
• ﻿X
• I have to figure out how far away from this dog I am!! I better figure it out using tangent. ﻿
• 31°﻿
• Tan(31) = 8/x, then I have to multiply by x on both sides, and after I will have to divide by Tan(31). After doing this, I come to the fact that my dog is 13.3 Inches away.
• Pet Store﻿
• I love Gerald. I wish that I could just walk with him forever!!
• Ruff Ruff
• Inverse Tangent﻿
• ﻿7
• I don't want to go get the ball, I hope Gerald gets it. But just in case, let me figure out what angle I'd have to walk to get it the fastest. I'll use inverse tangent to do it!
• ﻿15
• Tan(x) = 15/7, so Tan(-1) = 15/7. This equals 65°, so I will have to walk at a 65° angle to get to the ball the fastest.
• Sin(x) = 100/137. which means that Sin(-1) = 100/137. This means that the angle is 46.9°.
• Inverse Sine﻿
• ﻿X°
• 100
• 137
• Wow, that's a really big house, I wonder what the angle from the top to the bottom is. I think I'm going to have to use my trigonometry skills of Inverse Sine to find out.
• ﻿Ruff Ruff!!
• I'm so excited to take my brand new dog Gerald home!!
• Sin(37)/x = Sin(23)/15, next I would Than I would cross multiply by the bottom numbers, making it 15(Sin(37)) & X(Sin(23)), making you divide by Sin(23) & the finl result would be that the car is 23 at a diagonal.
• ﻿21
• ﻿15
• ﻿X°
• ﻿37°
• ﻿Inverse Cosine
• ﻿X
• 38﻿
• ﻿Now I just have to get into the garage. Let me make sure that I'm going to fit. I need to measure the garage and my car. I'm going to use the law of sines and inverse cosine to find it!
• Law of Sines﻿
• ﻿23°
