Answer:
210° , 330°
Step-by-step explanation:
using the sides of the 30- 60- 90 triangle
with legs 1,
and hypotenuse 2 , then
= 30° ← related acute angle
since
- 
then angle is in third / fourth quadrants , then required angles are
180° + 30° = 210° ← in third quadrant
360° - 30° = 330° ← in fourth quadrant
sqrt (100) is a rational number
10*10 = 100 (-10)*(-10) =100
sqrt(100)
=-10, 10
these are rational numbers
