Need help finding n forgot how to do this

andreyandreev [35.5K]

Answer:

$n = 3\sqrt{2}$

There are two best ways to solve this.

using cosine method:

$cos(n) = \frac{adjacent}{hypotenuse}$

$cos(60) = \frac{adjacent}{6\sqrt{2} }$

$adjacent,n = cos(60) * 6\sqrt{2}$

$n = 3\sqrt{2}$

using sine method:

$sin(n) = \frac{opposite}{hypotenuse}$

$sin(30)= \frac{n}{6\sqrt{2} }$

$n = sin(30) * 6\sqrt{2}$

$n = 3\sqrt{2}$

There are many ways, not to make it complex, these are the best ways to solve for n. Hope it helps ~

Answer:

Step-by-step explanation:

The function will be zero when the numerator is equal to 0. So, set the numerator equal to 0 and solve:

$0 = 4 {x}^{2} - 36x$

I will use the quadratic formula:

$\frac{ 36 + \sqrt{ {36}^{2} - 4(4)(0)} }{2(4)} \\ \frac{ 36 + 36}{8} = 9$

Therefore, x = 9 is a 0. Let's check with subtracted root now:

$\frac{ 36 - \sqrt{ {36}^{2} - 4(4)(0)} }{2(4)} \\ \frac{ 36 - 36}{8} = 0$

It appears 0 is also a root.

Therefore, the answer is D.

Help me please !!!!! ASAP !

Answer:

x = 6 sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2+ x^2 = 12^2

36 + x^2 = 144

Subtract 36 from each side

x^2 = 144-36

x^2 =108

Take the square root of each side

sqrt(x^2) = sqrt(108)

x = sqrt(36*3)

x = 6 sqrt(3)
