Answer:
I'm well I can't include a model but I think I could explain it pretty well you see when you add the six tiger shark teeth and the eight sand tiger shark teeth together and compare that to the 18 that is 14 so they said the rest is well the rest is bull shark teeth so that is for so the ratio is 4 to 18 which means the 4 stands for the bull shark teeth to the whole amount of shark teeth
9. You need an exact answer. So I will give you it but I'll also give you an approximation because it might help you understand it more.
Because we know the cosine fo theta, we can evaluate the inverse cosine of -2/3 first to find theta.
= 131.81° approx.
Because 131.81° is in the second quadrant its third quadrant partner is 228.19°. Which would make the sine 0.75 approximately.
But we need an exact answer I suppose so which is this disgusting mess...
. I know it looks scary but it is basically all the steps we just did but without evaluating anything.
This can be simplified using: sin(x− y) = sinxcosy−cosxsiny
To... 
answer:
10. Okay. So because we have a point we can say that...
θ = 
sin(θ) = +sin()
11. arcsin(-0.37) = 
= -21.72°+2kπ or 201.72°+2kπ approx. where k has to be an integer
answer: idk if you want one or more solutions so I gave you them all.
12. arccos(-√3/2) = 
Remember that "k" must be an integer.
answer: 5π/6
Answer:
is their answers? that we can see or a pic?
Answer:
25.61 ?
Step-by-step explanation:
use Pythagoreans theorem
a^2+b^2=c^2
20^2+16^2=656
sqrt 656=25.61
X + 5 + 11x = 12x + y
Simplify: 12x + 5 = 12x + y (We are adding x and 11x on the left side)
Subtract 12x from each side makes each zero.
5 = y
So we can plug in and test. I'm picking two random numbers to plug in for x. 10, and 82
x = 10, y = 5
10 + 5 + 11(10) = 12(10) + 5
125 = 125
x = 82, y = 5
82 + 5 + 11(82) = 12(82) + 5
989 = 989
So we verified y = 5
