Answer:
tan x = 3/4.
Explanation:
We know sin means 
 in a right triangle. This means that the Hypotenuse= 5, and the Opposite side= 3.
 in a right triangle. This means that the Hypotenuse= 5, and the Opposite side= 3.
Using Pythagorean theorem, we can determine that the 'Adjacent' side= 4.
The formula for 'tan' is 
 . If we plug in our values, we get:
. If we plug in our values, we get:
