Answers:
∠A=45° & ∠B=45°
Step-by-step explanation:
In triangle ABC, all angles are less than 180° but their sum is 180°
For the trigonometric statements
sin(A)=cos(B)
sin(B)=cos(A)
These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.
Hence, both angles are of 45°

Answer:
39
Step-by-step explanation:
the first three call 3, making it 3*3, then each of them will get 3 more, making it 3+(3*3)+(3*3*3),3+9+27, 39
In a 2-way frequency table, you take the row entry and divide it by its row total to get a decimal.
For your example:
It starts out like this:
sunny snowy
Male: 17 11
Female: 15 16
Add the rows up.
sunny snowy total
Male: 17 11 28
Female: 15 16 31
Then divide the number the by the total:
sunny snowy total
Male: 17/28 11/28 28
Female: 15/31 16/31 31
Yours says to round to the 1000th place, so it ends up like:
sunny snowy
Male: .607 .393
Female: .484 .515
Hope that helps!!
I believe that the answer to that one would be A.
