i'll try :D

Answer 4

if sin theta= square root of 3/2 which of these could not be the value of theta
60 degrees
120 derees
240 degrees
420 degrees

Answer 5

for which value of theta is tan theta equal to sin theta
pi
pi/2
pi/4
pi/6

Answer 6

Actually i have no idea i'd have to look all over geometry again and i currently have no time for that xD i just knew that sinus = opposite side / hypotenuse and the opposite side = 0 since 180 degrees is just a line. 0 divide by whatever is always zero.

Maybe somebody with more knowledge of geometry could explain better
