In right triangle XYZ, triangle Y is the right angle and m angleX = 60 degrees. If YZ= 4 what is XY

Marina86 [1]

Answer:

$XY = \frac{4\sqrt 3}{3}$

Step-by-step explanation:

<em>The question is illustrated with the attached figure.</em>

Required

Determine XY

To solve for XY, we make use of the tan function, which states that:

$tan\theta = \frac{Opposite}{Hypotenuse}$

In this case:

$tan\ 60= \frac{YZ}{XY}$

Substitute 4 for YZ

$tan\ 60= \frac{4}{XY}$

Make XY the subject

$XY= \frac{4}{tan\ 60}$

$tan\ 60 =\sqrt 3$

So, the expression becomes:

$XY = \frac{4}{\sqrt 3}$

Rationalize:

$XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}$

$XY = \frac{4\sqrt 3}{3}$

What is the solution of log2 (3x-7) =3

Valentin [98]

Answer:

x = 5

Step-by-step explanation:

because the log is base 2 you can remove the log by raing 2 to the power of each side:

$2^{log2 (3x-7)} = 2^{3}$

the 2 and log2 cancel leaving:

$3x-7 = 2^{3}$

this means we can now solve through simple algebra:

$3x-7 = 8\\3x = 8 + 7\\3x = 15\\3x/3 =15/3\\x = 5$

When n is divided by 12,the remainder is 6.What is the remainder when n is divided by 6?

trapecia [35]

For some number to be divisible by 12 it has to be divisible by 6 and by 2.
we can write number n as:

n = 6 + 12*k where k is positive integer.
If we divide n by 12 we will get remainder 6 because 12*k part is divisible by 12.
The part 12*k is as said divisible by 12 which means it is divisible by 6 (as first stated) and it has remainder 0. That leaves us with 6/6 which again has 0 as remainder. That means that number n is divisible by 6

The answer is 0
