Answer:
Theoretical probability is what that you expect to happen to you while experimental is what actually happen when you try it out.
Answer:
tita = 0 , 180, 270, 360. ( tita = 0 ≤ x ≤ 360).
Step-by-step explanation:
sin tita + sin ^2 tita = 0
sin tita( sin tita + 1) = 0
sin tita = 0, - 1.
For angles between 0 and 360 inclusive sin = 0 gives 0, 180 and 360 degrees. The angle whose sine is -1 is 270 degrees.
tita = 0 , 180, 270, 360.
