Question

25 m, 15 m, b. what is the length of the missing leg? if necessary, round to the nearest tenth. b = meters

Explanation:

Step1: Apply Pythagorean theorem

Let hypotenuse $c=25$, one leg $a=15$, missing leg $b$. Theorem: $a^2 + b^2 = c^2$
Rearrange for $b$: $b = \sqrt{c^2 - a^2}$

Step2: Calculate values

Substitute: $b = \sqrt{25^2 - 15^2} = \sqrt{625 - 225} = \sqrt{400} = 20$

Answer:

20
