  93. Confuses how my teacher got this?

    The question says "Given that cos(theta)=(-7/25) and sin(theta)>0, calculate the exact values of tan(theta) and csc(theta). We start out by drawing a triangle. 25 is on the side of the hypotenuse and -7 is on the adjacent side, because cos is adjacent over
