Question

score: 1/10 current time: 67.8 find: cos a the figure is not drawn to scale answer 24/74 70/74 24/70 70/24

Explanation:

Step1: Recall cosine - ratio definition

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For angle $A$, the adjacent side to angle $A$ is 24 and the hypotenuse is 74.

Step2: Calculate $\cos A$

$\cos A=\frac{24}{74}$

Answer:

$\frac{24}{74}$
