Answer:
The length of the longer leg is ![7\sqrt{3}\ units](https://tex.z-dn.net/?f=7%5Csqrt%7B3%7D%5C%20units)
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In any triangle:
The shortest side is always opposite the smallest interior angle. The longest side is always opposite the largest interior angle
so
The longer leg is AC
we have
----> by SOH (opposite side divided by the hypotenuse)
Remember that
![sin(60^o)=\frac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=sin%2860%5Eo%29%3D%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)
![AB=14\ units](https://tex.z-dn.net/?f=AB%3D14%5C%20units)
substitute the given values
![\frac{\sqrt{3}}{2}=\frac{AC}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%3D%5Cfrac%7BAC%7D%7B14%7D)
![AC=7\sqrt{3}\ units](https://tex.z-dn.net/?f=AC%3D7%5Csqrt%7B3%7D%5C%20units)
The answer is 20p. P represents the number of boxes she buys and 20 is how many pens are in each box.
