• ...Meanwhile, outside.﻿
• Oppsite of angle 30 is 8. And the hypotenuse of angle 30 is 17.
• 17﻿ hypotenuse
• 30°﻿
• 8 opposite﻿
• So in this case sin30° = 8 / 17
• 17﻿ hypotenuse 17﻿ hypotenuse
• So in this case, sin30°= 8 / 17.﻿
• 30°﻿ 30°﻿
• 8 opposite﻿ 8 opposite﻿
• Do you understand now Jimmy?
• 17﻿ hypotenuse 17﻿ hypotenuse 17﻿ hypotenuse
• So in this case, sin30°= 8 / 17.﻿ So in this case, sin30°= 8 / 17.﻿

• Yes Professor Avalos, but I was talking about the sign on the desk.
• 8 opposite﻿ 8 opposite﻿ 8 opposite﻿
• Ah.  Excellent question once again Jimmy.  Allow me to explain.
