#### Storyboard Text

• This is Sam. Sam has decided to make a new skating ramp illegally. ﻿
• The ramp will end on this point of the building. For it to be safe it has to have an angle of ﻿67 from the ground.
• The building is 30ft tall.﻿
• Knowing the building is 30 ft long and having 2 angles, the 67 degree angle and 90 degree angle find how long he had to make the ramp (Hypotenuse).﻿
• Sam uses trigonometry, he remembers that the inside angles of a triangle equal 180, using the angles he knows he finds what the third angle is.﻿
• 180 minus 90 equals 90 and 90 minus 67 equals 23! ﻿
• Sam then uses trigonometry to find how long the board he needs is going to be.﻿
• sin67 divided by 30 equals ﻿32.6 if I multiply it by sin90 it equadls 32.6
• I don't have a board that long......﻿
