<h2>See the explanation.</h2>Step-by-step explanation:
It is told that, 330 students that are surveyed, are 9th graders.
Hence, 0.55 represents 330 students, that is 1 represents = 600 students.
The number of 9th grade students whose favorite elective is music is represented by 0.18.
1 ≡ 600
0.18 ≡ = 108.
The percentage of students whose favorite elective is home economics and are also in 10th grade is = 6%.

Step-by-step explanation:
Sinθ =
If, sinθ = - and π < θ <
Since, sinθ is negative, angle θ will be in IIIrd quadrant.
And the measure of angle θ will be (180° + 30°)
θ = 210°
It's necessary to remember that tangent and cotangent of angle θ in quadrant III are positive.
Therefore, cos(210°) =
tan(210°) =
csc(210°) =
sec(210°) =
cot(210°) = √3
