Answer with explanation:
P=An Accurate order can contain orders from many of the restaurants, that is either from Restaurant A, Restaurant B,C,.D,........
P={A,B,C,D,E,F,G,......}
And taking an order from restaurant A, is another event.
Q={A}
→P ∩ Q={A}
Which is not disjoint.
This can be explained with the help of Venn diagram also.
Answer:
a) 45° cause tan = sin/cos and sin 45 and cos 45 both give square root 2/2
b) 120°
c) sin = -1/2 = -30° or 330° both are same
Use the trig circle which i have included in the answer to better understand trig angles
hope that answers your question
I want to let you know that each angle has sets of coordinates the left number is cos and right is sin. Ex) sin of 30 is 1/2 and cos of 30 is square root 3/2 In case you dont fully understand dont hesitate to comment.
good luck!!
