Answer:
c. 9/12
Step by step explanation.
Given: sin = 9/15
and,
![sin = \frac{opp.}{hyp.}](https://tex.z-dn.net/?f=sin%20%3D%20%20%5Cfrac%7Bopp.%7D%7Bhyp.%7D%20)
![tan = \frac{opp.}{adj.}](https://tex.z-dn.net/?f=tan%20%3D%20%20%5Cfrac%7Bopp.%7D%7Badj.%7D%20)
thus, find adj. side
by using Pythagoras theorem
![{c }^{2} = {a}^{2} + {b}^{2}](https://tex.z-dn.net/?f=%20%7Bc%20%7D%5E%7B2%7D%20%3D%20%20%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20)
then,
let adj. side be a^
![{a}^{2} = {c}^{2} - {b }^{2} \\ {a}^{2} = {15 }^{2} - {9}^{2} \\ {a}^{2} = 144 \\ a = 12](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20%20-%20%20%7Bb%20%7D%5E%7B2%7D%20%5C%5C%20%20%7Ba%7D%5E%7B2%7D%20%20%20%3D%20%20%7B15%20%7D%5E%7B2%7D%20%20-%20%20%7B9%7D%5E%7B2%7D%20%20%5C%5C%20%20%7Ba%7D%5E%7B2%7D%20%20%3D%20144%20%5C%5C%20a%20%3D%2012)
thus,
adj. side is 12
then,
tan of the angle = 9/12
