You can take this further. cos30cosA + sin30sinA + sin60cosA + cos60sinA cosA(cos30 + sin60) + sinA(sin30 + cos60) cosA(√3/2 + √3/2) + sinA(1/2 + 1/2) √3cosA + sinA

It seems a little vague, but I'm assuming it is the sum and difference formulas. If that's the case than this is what it would be:(((cos 30º • cos A) + (sin 30º • sin A))                              +  ((sin 60º • cos A) + (cos 60º • sin A)))From their you can simplify and solve.

that last entry didn't turn out like I expected. Let me try it again with simpler symbols:(((cos 30 * cos A) + (sin 30 * sin A))                              +  ((sin 60 * cos A) + (cos 60 * sin A)))
