A right triangle has a hypotenuse length of 13 units. One leg has a length of 12 units. Which equation can be used to determine
viktelen [127]

a = √(13² - 12²) units

<h3>Further explanation</h3>

<u>Given:</u>

  • A right triangle has a hypotenuse length of 13 units.
  • One leg has a length of 12 units

<u>Question:</u>

Which equation can be used to determine the length of the other leg?

<u>The Process:</u>

We will solve a problem regarding right triangles. In the process, there is a relationship between the Pythagorean Theorem with Exponent and Square Root.

Let us find out the equation to determine the length of the other leg. Let the length of the leg as "a".

The Phytagorean Theorem:

\boxed{ \ (leg)^2 + (leg)^2 = (hypotenuse)^2 \ }

\boxed{ \ a^2 + 12^2 = 13^2 \ }

Subtract by 12² on both sides.

\boxed{ \ a^2 = 13^2 - 12^2 \ }

To take the square root on both sides.

So here's the equation that can be used to determine the length of the other leg: \boxed{\boxed{ \ a = \sqrt{13^2 - 12^2} \ }}

- - - - - - - - - -

Notes

If we continue working on the above, the results will be as follows:

\boxed{ \ a = \sqrt{13^2 - 12^2} \ }

\boxed{ \ a = \sqrt{169 - 144} \ }

\boxed{ \ a = \sqrt{25} \ }

Hence the length of the other leg equal to a = 5 cm.

Of course, we agree with the use of the right intuition, which is to remember Pythagorean Triples, i.e., \boxed{ \ 5-12-13 \ }. This method is very convenient when working on multiple-choice tests in a limited amount of time.

Use the formula v=5to the third power where v is the volume and s is the edge length of the cube to solve this problem what is t
elena-s [515]
If I'm really it correctly, V = 5^3
v = s^3
s = 5
V = 5*5*5
V = 25*5 That's 2 fives multiplied together.
V = 125 cubic units.

PLEASE PLEASE PLEASE PLEASE (5'1, 5'2, 5'3, 5'4, 5'5, 5'6, 5'7, 5'8, 5'9, 5'9, 5'10, 5'11, 5'12)
Yakvenalex [24]

Answer:5

5 feet 7 inches

Step-by-step explanation:

first add all of the given together and then divide what you get by the number of terms given

(5'2+5'3+5'4+ 5'5+5'6+ 5'7+ 5'8+5'9+5'9,+5'10+5'11+5'12)/12 = 5'7 11/64 inches

then divide 11 by 64 on a calculator and then round the decimal you get to the nearest tenth which gives you the answer 5 feet 7 inches.
