Answer:
, 
Explanation:
2√2 sin(q) + 2 = 0
2√2 sin(q) = -2
sin(q) =
sin(q) =
Now, we know that:
sin (45) =
From the ASTC rule, we know that the sine function is negative in the third and fourth quadrant.
This means that:
either q = 90 + 45 = 135° which is equivalent to
or q = 270 + 45 = 315° which is equivalent to
Hope this helps :)

1. (x + 6)(x + -12)
2. (x + 10)(x - 10) = x² - 100
3. (x - 6)(x + 17) = x² + 11x - 102
4. (-x + 8)(x - 5) = -x² + 13x - 40
5. (x + 13)(x + 8) = x² + 21x + 104
6. (x + 2)(x + 7) = x² + 9x + 14
2. (x + 10)(x - 10) = x² - 100
3. (x - 6)(x + 17) = x² + 11x - 102
4. (-x + 8)(x - 5) = -x² + 13x - 40
