Wow, 48 is E?
I would've went for sin first, since it's on the y-axis, but that's weird, we never talked about [unparseable or potentially dangerous latex formula] inside trig functions.
For 55, I would set one vector on the x axis, then solve. They give you the angle between, so putting one on the x-axis simplifies somewhat.
[unparseable or potentially dangerous latex formula], then find x and y, then take the magnitude, [unparseable or potentially dangerous latex formula].
