Answer:
210°
Step-by-step explanation:
Given
sinΘ = - 
Note taken the inverse sine of the positive value of the ratio, gives the related acute angle, that is
Θ = 
( ) = 30° ← related acute angle
Thus the required angle in the third quadrant is
Θ = 180° + 30° = 210°

Answer:
c = 81
Step-by-step explanation:
The equation x² -c = 0 can be factored as ...
(x -√c)(x +√c) = 0
which has roots ±√c.
The roots are given as ±9, so we have ...
±9 = ±√c
c = (±9)² = 81
The value c = 81 makes the equation have ±9 as solutions.
