Hello Delanew,

Do you mean the altitude of the triangle, since you are already given the length?

If you are looking for an altitude, you can start by drawing it in your triangle. You will see that it divides the triangle into two 30, 60, 90 triangles. The short leg of the triangle is 6, so using the rules for a 30, 60, 90 triangle the longer leg (your altitude) would be 6 square roots of 3. Or about 10.39.

If this isn't what you are looking for, let me know.
I can try and help.

Good luck!

Answer:

Step-by-step explanation:

Let's assume that Nancy bought 'p' numbers of platies. The question says, she buys goldfish, 4 more than twice the number of platies.

So, 4 more than twice of 'p' can be written as,

$2p+4$ that is the number of goldfish she bought. Let 'g' represent the number of goldfish. So we have,

$g=2p+4$

She also buys 2 black mollies and a few guppies that amounted to one quarter of the total number of goldfish she bought. Let 'x' represent the number of guppies, so we have,

$x= \frac{1}{4} (2p+4)$
