Best ResponseYou've already chosen the best response.2we take inverse of ratio to find an angle so you need an angle when cos theta = sqrt{3}/2 1st) you can use unit circle 2nd) calculator 3rd) familiar with 30690 /454590 triangle theorem

Best ResponseYou've already chosen the best response.2there should be two angle when cos =sqrt{3}/2 remember it's reflected over they axis dw:1444053390030:dw

Best ResponseYou've already chosen the best response.2well there are two you should write both as an ansaawer just in case if they are looking for more than one value hmm

Best ResponseYou've already chosen the best response.2right when we need an angle we take invs of ratio so that's why it's arccos

Best ResponseYou've already chosen the best response.2ohh okay formula to convert degree to radian \[\huge\rm rad=\frac{ \pi}{ 180} \times degree \]
