Question: 1 / 400

What is the result of calculating the value of c using the Pythagorean Theorem for legs of 50 feet and 80 feet?

80 feet

85 feet

89 feet

94 feet

To determine the length of the hypotenuse $ c $ using the Pythagorean Theorem, you can apply the formula:

c = \sqrt{a^2 + b^2}

where $ a $ and $ b $ are the lengths of the two legs of the right triangle. In this case, the legs are given as 50 feet and 80 feet.

First, calculate $ a^2 $ and $ b^2 $:

50^2 = 2500

80^2 = 6400

Next, add these two values together:

2500 + 6400 = 8900

Now, take the square root of this sum to find $ c $:

c = \sqrt{8900}

Calculating the square root gives:

c \approx 94.34

Since the choices provided are rounded values, the closest value is approximately 94 feet, confirming the correctness of that answer. The other options do not reflect the accurate calculation based on the Pythagorean Theorem, hence they do not match the expected value derived from the equation.
