You can put this solution on YOUR website! csc A =−5,
270° < A < 360° find the other five trigonometric functions
***
Reference angle (A) is in quadrant IV where sin<0, cos>0, and tan<0
sin A=(1/csc A)=-1/5
cos A=√(1-sin^2(A))=√(1-1/25)=√(24/25)=√24/5
sec A=1/cos A=5/√24=5√24/24
tan A=sin/cos=-1/√24=-√24/24
cot A=1/tan A=-√24
