Holly's stock had the following changes in value over a week: +9, -6, -2, +5, -1. What was the total change by the end of the week?

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

(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

addition
