I need help with 18 & 19

(0, 0), in What 18. On the unit circle with its center at (0, 0), an arc with central point P(1, 0) and terminal point T(3, ") has length x. a. T is located in which quadrant? b. sin x = e . CSC x C. COS X = f . sec x = d. tan x = g. cot x = 19. Find the values of the six trigonometric functions of e if e is an angle in standard position with T(-20, -21) on its terminal ray. a. 0 is located in which quadrant? b. sin 0 = e . CSC 0 = C. COS 0 = f. sec 0 = d. tan 0 = g. cot 0 = + turn in radians per
