Question

what is the length of the hypotenuse? if necessary, round to the nearest tenth.
$c = \square$ inches

Explanation:

Step1: Apply Pythagorean theorem

$$c^2 = a^2 + b^2$$

Step2: Substitute side lengths

$$c^2 = 2^2 + 2^2 = 4 + 4 = 8$$

Step3: Solve for c

$$c = \sqrt{8} \approx 2.8$$

Answer:

2.8 inches
