I won't give you the exact answers, but I will give you hints that you should use to EASILY solve them.

 

Remember:                 (ex: Sin(D)=\(\frac{9}{15}\Rightarrow\boxed{\frac{3}{5}}\))


Sine Ratio is \(\frac{Opposite}{Hypotenuse}\)

 

Cosine Ratio is \(\frac{Adjacent}{Hypotenuse}\)

 

Tangent Ratio is \(\frac{Opposite}{Adjacent}\)

 

Also remember:              (ex: Csc(D)=\(\frac{1}{\frac{3}{5}}\Rightarrow\boxed{\frac{5}{3}}\)

 

Secant is \(\frac{1}{Cosine}\)

 

Cosecant is \(\frac{1}{Sine}\)

 

Cotangent is \(\frac{1}{Tangent}\)
