I need help with the following exercises:

1) The angle that measured -200 degrees is equivalent to?

a) 1

d) 2

c) 1

4) Find the angle X measure in degrees in where x= 163

Theta=-10/3

TO convert it to radian we have to multiply it by pi/180

-200 * pi/180 = -10 pi/9

Hence the correct option is b

2. csc (7pi/3) = csc(2pi + pi/3) = 1/sin(2pi + pi/3) = 1/sin(pi/3) = 2/sqrt3 =2sqrt3/3
