Answer

sin B = $\frac{\sqrt {33}}{7}$ cos B = $\frac{4}{7}$ tan B = $\frac{\sqrt {33}}{4}$

Work Step by Step

Let's set up the trigonometric ratios. The ratio for sine is: sin θ = $\frac{opposite}{hypotenuse}$ The ratio for cosine is: cos θ = $\frac{adjacent}{hypotenuse}$ The ratio for tangent is: tan θ = $\frac{opposite}{adjacent}$ Let's plug in our values: sin B = $\frac{\sqrt {33}}{7}$ cos B = $\frac{4}{7}$ tan B = $\frac{\sqrt {33}}{4}$
