Question

score: 4/10 current time: 66.0 find: cos b the figure is not drawn to scale answer 48/36 36/48 48/60 36/60

Explanation:

Step1: Recall cosine - ratio definition

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For angle $B$, the adjacent side to angle $B$ is 48 and the hypotenuse is 60.

Step2: Calculate $\cos B$

$\cos B=\frac{48}{60}$

Answer:

$\frac{48}{60}$
