2.4 degrees or 2.4 radians ?

sin = -4/5 so in quadrant 3 or 4

tan is negative so in quadrant 4

hypotenuse = 5

opposite = 4

adjacent = 3

so cos theta = 3/5

and theta = -53.1 or -.93 radians

2. Is the 2.4 in radians?

14. The question is incomplete.

Theta is in the fourth quadrant, sin^-1 4/5 below the +x axis.
