how do we know what cos inverse is when it can't be gotten on jamb calculator

resultant velocity more like resultant vector is 20, right
the flow is 12.
if you remember your vectors correctly. 20 is the HYP while 12 is the adj. the angle is then between 20 and 12 I. e between the hyp a d adj. therefore u use COS °
