Answer:
we will use Pythagorean's Theorem
[tex]25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15[/tex]
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
[tex]25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15[/tex]
Therefore, the missing leg is 15 meters long.
Answer:
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 b.
To solve this problem, we need to use Pythagorean's Theorem
[tex]25^{2}=20^{2}+b^{2}\\ b=\sqrt{25^{2}-20^{2}}\\ b=\sqrt{625-400} =\sqrt{225}\\ b=15[/tex]
Therefore, the leg missing is 15 meters long.
