4 0

Given:
2, 4, 9, 11, 16, 18, 23

From 2 to 4 you can see that you go up 2, and then from 4 to 9 you go up 5. If you continue down the line you can see that the pattern of +2, then +5 goes on. Therefore, the pattern is +2 then +5.

I hope this helps!

Find sin 0, where is the angle shown. Give an exact value, not a decimal approximation.

Answer:

$\displaystyle \sin\theta=\frac{12}{13}$

Step-by-step explanation:

Recall that in a right triangle, sine is the ratio of the opposite side to the hypotenuse:

$\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$

We are actually not given the opposite side in this case. However, since we know the hypotenuse and the adjacent side, we can use the Pythagorean Theorem to find the opposite side. So:

$a^2+b^2=c^2$
