#### Storyboard Text

• Study Date
• Alright Class. There's a test tomorrow so study
• So lets talk about Trigonometry.﻿ No worries.
• ﻿I'm pretty bad at Trig
• First the two sides we know are Opposite (300) and Adjacent (400).SOHCAHTOA tells us we must use Tangent. Next we will calculate Opposite over Adjacent. Next we calculate for the angle using tan-1 ﻿So the answer we will get is Angle X equals 36.9
• So we have to find the angle of elevation of the plane from point A on the ground
• A﻿
• ﻿X
• 400﻿
• 300
• ﻿O.K so what do we do first?
• ﻿300/400 =0.75 tan-1 of 0.75 = 36.9°
• Thanks for the help. So would you like to do this again sometime?
• ﻿Oh I think i can squeeze you into my schedule
• ﻿END?
