What is sin B ?

Neporo4naja [7]

Answer:

The answer to your question is sin B = $\frac{8}{17}$

Step-by-step explanation:

Sine is the trigonometric function that relates the opposite side and the hypotenuse.

In the picture, we have the hypotenuse and the adjacent side, so we must calculate the opposite side using the Pythagorean theorem.

b² = c² - a²

b² = 17² - 15²

b² = 289 - 225

b² = 64

b = 8

Now, we can calculate the sine

sin B = $\frac{opposite side}{hypotenuse}$

sin B = $\frac{8}{17}$
