Trigonometric functions aren't to do with triangles specifically, they are to do with angles.

So no, they aren't only for right angled triangles.

For example, the formula (1/2)ab * sin(c) calculates the area of a triangle, and will work on isosceles and scalene triangles.

Answer:

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Step-by-step explanation:

$\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix} +X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}$

$X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}-\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix}$

$X = \begin{bmatrix} - 5-(-1) & - 1-(-2)\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 5+1 & - 1+2\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Answer: 27 candles.

Step-by-step explanation:

A rectangular prism has a volume calculated by length x width x height.

In this case, the candles have a volume of 220 cm³.

If the company used 5940 cm³ of wax, to find how many candles they made, you just divide them:

$5940 / 220 = 27$

You get 27 candles.
