Question

find tan a
a. 4.5556
c. 4.4444
b. 0.225
d. 1.025
please select the best answer from the choices provided

Explanation:

Step1: Recall tangent formula

In a right - triangle, $\tan A=\frac{\text{opposite}}{\text{adjacent}}$. For angle $A$, the opposite side to angle $A$ is $BC = 9$ and the adjacent side is $AB=40$.

Step2: Calculate $\tan A$

$\tan A=\frac{BC}{AB}=\frac{9}{40}= 0.225$

Answer:

B. 0.225
