Answer:

<h2>The leg missing is 15 meters long.</h2>

Step-by-step explanation:

We know that one leg of the triangle is 20 meters long, the hypothenuse is 25 meters long, and the leg missing is called <em>b</em>.

To solve this problem, we need to use Pythagorean's Theorem

25^{2}=20^{2}+b^{2}\\ b=\sqrt{25^{2}-20^{2}}\\ b=\sqrt{625-400} =\sqrt{225}\\ b=15

Therefore, the leg missing is 15 meters long.

Answer:

we will use Pythagorean's Theorem

25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15

Therefore, the missing leg is  15 meters long.

Step-by-step explanation:

we will use pythagoras theorem

Given that,

One leg of the triangle is 20 meters long,

the hypothenuse is 25 meters long,

and the leg missing is called x.

we will use Pythagorean's Theorem

25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15

Therefore, the missing leg is  15 meters long.
