1 answer:
Answer: sin=7/13,cos=2.sqrt30/13
Step-by-step explanation:
SOH COH TOA
sin=opp/hyp,cos=adj/hyp
Use pyth. theorem to find the adjacent of C.
13^2 =7^ + b^2
169 = 49 + b^2
120 = b^2
sqrt120 = sqrtb
2.sqrt30 = b is the missing side.

A good way of doing this problem would be to use cross multiplication of ratios
<u />
Then cross multiply
(10 girls)(270 students)=(X girls)(18 students)
2700=18x
150=x
select the one that says "no, the estimate should be higher."
