C.

In a proportion your numbers increase by the product of the proportion. So if at one point in your graph you had (2,20), the proportion is 10 (2*10=20). Therefore your next points should be 3,30 ;4,40 ; 5,50. Etc.

Step-by-step explanation:

I almost thought this was going to be Pythagorean Theorem, but no.

Use Cosine Law:

cos θ = $\frac{10^2 + 21^2 - 17^2}{2(10)(21)}$

θ = cos−1(0.6)

θ = 53.130...

Now use the SOHCAHTOA ratio for sine ( $\frac{opposite}{hypotenuse}$ ) to find x now that you have one angle:

sin θ = $\frac{x}{10}$

x = 10sinθ (θ isn't needed to be written out as it is shown in the equation above)

x = 8
