- Homework Statement
- I noticed that when I do a calculation of the form 85-90 it gives a result of -5, which affects my overall answer by giving a negative number. I think I didn't correctly determine the angle of my muscle strength. Would it be possible for this angle to be 0ยฐ? So, by doing the 85-0 calculation, we would get a positive number.

ฮฃ๐น๐ฅ = 0
โ๐น๐๐ฅ + ๐น๐ sin (๐ฝ โ 90ยฐ) + ๐น๐๐ sin (180 โ ๐ฝ โ ๐) = 0
๐น๐๐ฅ = ๐น๐ sin ( ๐ฝ โ 90ยฐ) +๐น๐๐ sin(180 โ ๐ฝ โ ๐)
๐น๐๐ฅ = 93.6650N sin (85 โ 90) + 28.11N sin(180 โ 85 โ 79)
