Let cos(a) = −5 13 with a in qiii and sin(b) = 3 5 with b in qi. Find sin(a − b), cos(a − b), and tan(a − b). In what quadrant does a − b terminate?.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

236 cm 16 time 12 = 192

6 times 7 = 42
