Jennifer 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. Jennifer needs to know whether this diving board is standing up straight or not. Jennifer measures the height of the diving board to be 9 feet. The pool is 12 feet across and she measures the diagonal from the other side of the pool to the top of the diving board to be 15 feet. Is the diving board at a 90 degree angle with the ground? Explain how you know.

Question

anonymous · Answer

6^2+9^2=15^2  if that is true than it is right if it is not then it is not straight

anonymous · Answer

Use the pythagorean theorem $$a^{2}+b^{2}=c^{2}$$where a=9, b=12, and c=15.  If the numbers make the statement tre, then the angle is 90 degrees.

anonymous · Answer

it is not 90 degrees.
