(Math never got easier!) No seriously help:)

Step-by-step explanation:

cosФ=0 then the angle=π/2=90 degrees

sinФ==1     sin 90=1

12) the original price of the console  that Amanda bought :

the price before the tariffs:

360-(360*50^)=180 dollars

What you do on the way home has nothing to do with what you have to do to get to work in the morning. So the answer you want is A.

There were no accidents to delay you. That's relevant. It helps getting you to work on time.
