Answer

Explanation:

Step1: Calculate the radius ( r )

For a point ((x,y)=(3, - 5)) on the terminal arm of an angle, use the formula ( r=\sqrt{x^{2}+y^{2}} ). [ r=\sqrt{3^{2}+(-5)^{2}}=\sqrt{9 + 25}=\sqrt{34} ]

Step2: Find the sine ratio

The formula for sine is ( \sin D=\frac{y}{r} ). Here ( y=-5 ) and ( r = \sqrt{34} ), so ( \sin D=\frac{-5}{\sqrt{34}} ).

Step3: Find the cosine ratio

The formula for cosine is ( \cos D=\frac{x}{r} ). Here ( x = 3 ) and ( r=\sqrt{34} ), so ( \cos D=\frac{3}{\sqrt{34}} ).

Step4: Find the tangent ratio

The formula for tangent is ( \tan D=\frac{y}{x} ). Here ( y=-5 ) and ( x = 3 ), so ( \tan D=\frac{-5}{3} ).

Answer:

C. ( \sin D=-\frac{5}{\sqrt{34}}, \cos D=\frac{3}{\sqrt{34}}, \tan D =-\frac{5}{3} )
