I need help trying to solve trigonometric identity problems
I just need help if someone could break it down step by step how to solve for:

if cos of theta is -3/5 find csc of theta

• Algebra 2 -

CosTheta=-3/5

so you know the adjacent side to Theta is -3, and the hypotensue is 5.
That makes the opposite side =-4,or +4

so, sinTheta=4/5 or -4/5

secTheta=-5/3

cscTheta=1/sin= 5/4 or -5/4

TanTheta=4/3 or -4/3

Theta is in quadrante II or III
