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.

The clock was exactly on time at 7am at 1pm the clock was 228 seconds late at that rate how slow was the clock half an hour

yan [13]

Answer:

19 seconds.

Step-by-step explanation:

Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:

1 PM = 13:00

13 - 7 = 6

228/6 = 38

38/2 = 19

Thus, every half hour the clock is delayed 19 seconds.
