#### Storyboard Text

• Hi my name is Lu Keran and I am fancinated in achritecture! Let me bring you around the city and show you what i mean!
• Here are some basics you need to know before we begin!
• ﻿Find angle using tan:given the side opposite to angle and adjacent sidetan(
• ﻿Find angle using cos:Given adjacent side and hypotenuse .cos(
• If they give us the Hypotenuse and ask us to find the adjacent side we need to reverse the process using cos.
• Find side using sin:gives the hypotenuse asks for the opposite side of anglesin=(
• ﻿Find angle using sin:given Short leg and Hypotenusesin(
• ﻿Find side using tan:given adjacent side asks to find side opposite of angletan(
• In this case is we are given the adjacent side and are asked to fine the side opposite of the angle we are asked to find the adjacent side using tan.
• ﻿AC= the opposite side of the angle
• 70
• 30 ft﻿
• tan (
• X
• You might be wondering why we need to measure this triangle well it is because for the contruction people need to know how tall to build the top ﻿﻿﻿of the building.
• In order to build this skate ramp at what angle must the ramp be at?
• BC= the side opposite to the angleAB= hypotenuse
• sin(
• If the diagram has given us the Hypotenuse and the side opposite to the angle then they are asking for use to find the angle using sin.
• ?
• what is the half the length of the bed?
• BC= adjacent sideAB= Hypotenuse (3.11)
• cos(
• 50
• 3.11 ft
• ?
• Welcome to the end of the tour Trigonometry might seem hard but its is just a bunch of memorizing formulas and plugging in numbers!
