Answer:
120° and 240°
Step-by-step explanation:
The given info about the angle x is cos x = - 1/2.
By definition, cos x = - 1/2 = (adjacent side) / hypotenuse, so here we can assume the adjacent side is -1 and the hypotenuse is 2.
A negative cosine tells us that the angle is in Quadrant II or Quadrant III.
If x is in Quadrant II, then its value is 120°
If x is in Quadrant III, then its value is 120° + 120°, or 240°

Answer:
3 − m = −2 (m + 6); m = −15 Yes
5 (p + 3) = −35; p = −4 No
8q = 3 (10 + q); q = 6 Yes
Step-by-step explanation:
3 − m = −2 (m + 6)
3 - m = -2m - 12
m = -15
Answer is Yes
5 (p + 3) = −35
5p + 15 = -35
5p = - 50
p = -10
Answer is No
8q = 3 (10 + q)
8q = 30 + 3q
5q = 30
q = 6
Answer is Yes
