Answer:
sin(-pi/2) = -1
Step-by-step explanation:
sin (pi/12) cos((7pi)/12) -cos (pi/12) sin((7pi)/12) = -1
cos(-pi/2) = 0
sin(-pi/2) = -1
cos((2pi)/3) = -1/2
sin((2pi)/3) = (√3)/2
Set up a proportion
90/x = 60/100
60x = 9000
x = 150
if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%
