# A triangle has two corners with angles of # (2 pi ) / 3 # and # ( pi )/ 4 #. If one side of the triangle has a length of #12 #, what is the largest possible area of the triangle?

Largest possible area of the triangle = 4.7321

The remaining angle:

I am assuming that length AB (12) is opposite the smallest angle.

To find the largest possible area of the triangle given two angles and one side length, we can use the formula for the area of a triangle: ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ).

First, let's find the height of the triangle. We know that the side opposite the ( \frac{\pi}{4} ) angle (45 degrees) is the base of the triangle. The height of the triangle corresponds to the perpendicular dropped from the opposite vertex to this base. We can find the height using trigonometry:

[ \text{height} = 12 \times \sin\left(\frac{2\pi}{3}\right) ]

Next, we need to find the length of the base of the triangle. Since the angles given are ( \frac{2\pi}{3} ) and ( \frac{\pi}{4} ), the third angle of the triangle can be found by subtracting the sum of the given angles from ( \pi ).

[ \text{Third angle} = \pi - \left(\frac{2\pi}{3} + \frac{\pi}{4}\right) ]

Now, we can use the law of sines to find the length of the base:

[ \frac{\text{side opposite the third angle}}{\sin(\text{third angle})} = \frac{12}{\sin(\text{third angle})} ]

Finally, we can calculate the area of the triangle using the formula ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ).

This will give us the largest possible area of the triangle.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
