= .


Then  =  =  =  =  =  = .


tan(theta) =  =  = .

Note that all ratios will be positive since  is in the 1st quadrant

With , it follows that: y (opposite) = 3, and r (hypotenuse) = 5. This represents a 3-4-5 right triangle, and so, x (adjacent) MUST BE 4.

Therefore the other 5 trig ratios are:

1)    

2)            3)  

4)            5)
