Compute the PI ratio of the following project with the WACC of 9%: `0 1 2 3 4 $ (1,800.00) $ 200.00 $ 100.00 $ 300.00 $ 900.00

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: (3,11) is your answer.
