You can put this solution on YOUR website! If tan (theta) = (-7/5) and sin (theta) < 0, then find
Given data shows that reference angle is in quadrant IV where sin<0 and cos>0
solve for hypotenuse of reference right triangle:
=√(7^2+5^2)=√(49+25)=√74
sin (theta)=-7/√74=-7√74/74
cos (theta)=5/√74=5√74/74
sec (theta)=√74/5
csc (theta)=-√74/7
cot (theta)=-5/7
