If sin β = 0.45, we have to find cos ( π/2 - β ).
We know that: sin x = cos ( 90° - x ), or sin x = cos ( π/2 - x ).
For example: sin 60° = cos 30°.
cos ( π/2 - β ) = sin β = 0.45

Sorry. Idk :P. Idididididididididididididididididididid. Oops sorry I dropped my keyboard.
Okay so do 5.60 times 8% on a calutor.
Answer:
-1,050
Step-by-step explanation: This is quite simple first we know that 2,100 is negative(-2,100) because it is descending/going down. So now we know that we can divide -2,100 by 2 which sums up to 1,050. But we are going to have to add a negative sign due to the fact that if the two integers you are dividing are opposite signs it would be negative. So if you add a negative sign to 1,050 it would be -1,050. Just to keep in mind that opposites make negative when dividing I will put the integer rules below.
