When solving for the hypotenuse, what is the formula used?

• a^2 - b^2 = c^2

• a^2 + b^2 = c^2

• a^2 + b^2 = c

• a + b = c^2

What is the result of solving the equation 3^2 + x^2 = 5^2?

• x = 3

• x = 6

• x = 4

• x = 5

In the problem where the base is unknown, what is the first step?

• Add the base to the hypotenuse.

• Subtract the base from the hypotenuse.

• Multiply the base by two.

• Divide the base into two equal parts.

What is the final value of X when solving for the base?
