don't worry about question 4, your answer is correct
\[\cos(49) = \frac{x}{55}~~~so~~~x = 55 \times \cos(49)\]
OpenStudy (anonymous):
and for 5 what was it because the answer i got was close
OpenStudy (campbell_st):
so for question 5, which ratio would you use..?
OpenStudy (anonymous):
calculate it equals 16.53

OpenStudy (campbell_st):
which ratio did you use for question 4 @danial.sheikh ?
OpenStudy (anonymous):
so tan27=34/x
OpenStudy (anonymous):
same as u did but answer is 16.53
OpenStudy (campbell_st):
tan is correct the question is
\[\tan(27) = \frac{34}{x}~~~so~~~~x = \frac{34}{\tan(27)}\]
OpenStudy (campbell_st):
perhaps you should check that your calculator in in degrees...

is it c?
OpenStudy (campbell_st):
so @danial.sheikh you said
\[\cos(49) = \frac{x}{55}\]
OpenStudy (anonymous):
oh it wasn't in degrees sorry
OpenStudy (campbell_st):
that's what my answer was..
OpenStudy (anonymous):
36.08 is correct
