Question

What is the length of the unknown leg in the right triangle?

25 m

20 m

5 m

5 m

O V45 m

15 m

Answer 1

The leg missing is 15 meters long.

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

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

Therefore, the leg missing is 15 meters long.

Answer 2

we will use Pythagorean's Theorem

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

Therefore, the missing leg is 15 meters long.

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=√(625-400) =√(225)\\\\ b=15`

Therefore, the missing leg is 15 meters long.
