Answer:
sin a = -3/5
Step-by-step explanation:
sin^2(a)+cos^2(a)=1
sin^2(a)+ (4/5)^2 = 1
sin^2(a) = 1 - 16/25 = 9/25
sin a = 3/5 ( in Quadrant 1)
In quadrat IV the sine is negative
so sin a = -3/5
Answer:
there are eight lateral faces in prism
You can find this by finding how much she would be paid per hour and then multiplying it by 6. So, you have $35 for the other days but on Sunday's it is that and then half of that added on just in one hour.
35+(1/2)(35)= 35+17.5=$52.5/hour
after you find this value you need to multiply it by 6 hours in order to be left with $315.
Now if you can just put a good word in for me at that job :)
