If we want to get B by itself, we need to "undo" every operation being done to it. Those operations are (in order):
- Multiplication by A
- Addition with 3C
To undo these then, we'll need to:
And, since this is an equation, we'll need to do both of those to the right side as well to keep everything equal. Here we go:
AB + 3C - 3C = D - 3C (subtracting 3C)
AB/A = (D - 3C)/A (dividing by A)
B = (D - 3C)/A
And we're done! If you'd like to see it formatted a little nicer, here's this:

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.
It would point up if increasing, pointing down if it’s decreasing. I’m not entirely sure
A.8,B.2,C.6
Step-by-step explanation:
because
X=A is Z add b is 8
4^4square root 2 is the answer
