Question

what is the length of the hypotenuse? if necessary, round to the nearest tenth. c = \boxed{} meters

Explanation:

Step1: Apply Pythagorean theorem

$$c^2 = (2.7)^2 + (8.9)^2$$

Step2: Calculate squares of legs

$$2.7^2 = 7.29, \quad 8.9^2 = 79.21$$

Step3: Sum the squares

$$c^2 = 7.29 + 79.21 = 86.5$$

Step4: Find square root

$$c = \sqrt{86.5} \approx 9.3$$

Answer:

9.3
