Which set of numbers could represent the lengths of the sides of a right triangle? a 8 9 10 b 2 3 4 c 12 15 20 d 9 40 45

I took this test and for D. I think you meant to put 9, 40, 41 which is the correct answer.

Step-by-step explanation:

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
