Answer:
C. 72
Step-by-step explanation:
your are given the adjacent length of 2.4 cm and the hypotenuse of 7.8cm
so we know cos = adjacent/ hypotenuse
so to find the angle of cos you use the inverse of cos^-1(2.4/7.8)
after typing into calculator you should get about 72
(1,4) because when you substitute 1 in for x and 4 for y, you get 5(1) - 7(4) or 5 - 28 which equals -23
