7. Given: f= ((7-5), (4,5), (-2,-10), (8,-1)} g = {(7,3), (4,-2), (3,8), (-5,6)} Find: g(f(7)) and (f×g×g)(7)​

Hnmmmn not sure

Hmmm i had this before , give me a sec

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
