Answer:
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
Answer:

Step-by-step explanation:
Answer:
3/7 =12/n
3n=7×12
3n=84
n=84÷3
n=28
3/7= t/21
3×21=7t
63=7t
t=63÷7
t=9
3/7 =k-1/2k+10
3(2k+10)=7(k-1)
6k+30=7k-7
k=37
Step-by-step explanation:
$8,000 + $1,500 = 9,500
So 9,500 x .6 = 5,700 dollars donated by trustee.
$9,500 + $5,700 = $15,200 dollars tota
