Know the Answer?

Bobby Owens · Answer 1

D. Because of the Pythagorean Theorem that says

a^2+b^2=c^2

12^2+15^2=18^2

144+225=324

369=324

This statement is false, so tees can't be the sides of a right triangle.

Kenny · Answer 2

12^2 + 15^=18^

144+225=324

Add 144 to 225 = 369

369=324

Divide 369 to 324 = 1.13888889

1.13 is your answer

D is a false statement
