Ben is a safety inspector for a family gym. Recently, guests have been complaining about the diving board saying that it is leaning towards the water. Ben needs to know whether this diving board is standing up straight or not. Ben measures the height of the diving board to be 15 feet. The pool is 13 feet across and he measures the diagonal from the other side of the pool to the top of the diving board to be 21 feet. Is the diving board at a 90 degree angle with the ground? Explain how you know.

Best ResponseYou've already chosen the best response.1Well, from the information given, we can use sine and cosine formulas to find the angles. Remember this SOHCAHTOA (sine = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/adjacent)

Best ResponseYou've already chosen the best response.1we'll say A=13ft, B=15ft, and C=21ft sin A = 13/21 that gives us 0.6190... which is about 38º

Best ResponseYou've already chosen the best response.1If you put your calculator to degree mode and then put in sine 38 it should give you 0.6156...

Best ResponseYou've already chosen the best response.1Okay well we'll still use A=13ft B=15ft and C=21ft \[13^{2}+15^{2}=21^{2}\] 169 + 225 = 441 394 = 441 It's not a right triangle
