Can you rearrange the formula for a triangle as 1/2bcSinA as opposed to 1/2abSinC
Yes you can, but I don't see how that would matter. When asked for the area of a non-right angled triangle, you will always be given 2 lengths and 1 angle. so it doesn't matter which is representative of what since you are just multiplying the lengths and the function of sine for the angle and then dividing by 2.

This one you had to figure out the angle using the cosine rule, so I couldn't rearrange the letters to make SinC SinA, I thought you could rearrange it in such a manner but I just wanted to make sure
