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

the length of the other leg?
Group of answer choices

LaTeX: a^2=12^2+13^2 a 2 = 12 2 + 13 2

LaTeX: a=\sqrt{13^2-12^2} a = 13 2 − 12 2

LaTeX: a^2=12^2-13^2 a 2 = 12 2 − 13 2

LaTeX: a=\sqrt{12^2+13^2} a = 12 2 + 13 2

We know that a²+b²=c²

So if you follow the pythagorean theorem,  we substitute the hypotenuse for c² and the leg (12) for either a² or b² because a and b are both legs, so it doesn't matter.

now we have a²+12²=13²  

But I usually take the shortcut..and instead of a²+12²=13²

I subtract 12² from 13² (it's the same thing)

After you subtract 13²-12²=a²...you find the square root of 13²-12²

so the answer is LaTeX: a=\sqrt{13^2-12^2}

a= square root of 13²-12²

Use the fact that 2 1/2 divide 1/8 =20 to find 2 1/2 divide 5/8
Tasya [4]

Answer:

4

Step-by-step explanation:

Given that 2\frac 1 2 \div \frac 1 8 =20

\Rightarrow \frac 5 2 \div \frac 1 8 =20

\Rightarrow \frac 5 2 \times 8 1 =20 \cdots(i)

Now, 2\frac 1 2 \div \frac 5 8 = \frac 5 2 \div \frac 5 8=\frac 5 2 \times \frac 8 5

This can be written as

\frac 5 2 \times \frac 8 5=\frac 5 2 \times \left( \frac 8 1 \times \frac 1 5\right) [as \frac 8 5=\frac 8 1 \times \frac 1 5]

=\left(\frac 5 2 \times \frac 8 1 \right)\times \frac 1 5

=20 \times \frac 1 5 [ by using equation (i)]

=4

Hence, 2\frac 1 2 \div \frac 5 8=4
