Question

17 km 15 km b what is the length of the missing leg? if necessary, round to the nearest tenth. b = kilometers

Explanation:

Step1: Apply Pythagorean theorem

$$a^2 + b^2 = c^2$$
Here, $a=15$, $c=17$, solve for $b$:
$$b^2 = c^2 - a^2$$

Step2: Substitute values

$$b^2 = 17^2 - 15^2$$
$$b^2 = 289 - 225$$
$$b^2 = 64$$

Step3: Calculate square root

$$b = \sqrt{64}$$

Answer:

8 kilometers
