Answer:
69.8°
Step-by-step explanation:
Since cosФ = -0.3456
Ф = cos⁻¹(-0.3456)
Ф = 110.2°
Since the angles are supplementary, let the acute angle be x
So, x + 110.2° = 180°
x = 180° - 110.2°
x = 69.8°
Answer:
8
Step-by-step explanation:
Well 2x=16 is the same as x=8 when you divide by 2. So the dot should be on 8.
Naeem is the correct answer
M< 3 = 180 - 60 - 90
m< 3 = 30
answer
30
Answer:
x = -1
Step-by-step explanation:
1.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
2.1 Solve : -2 = 0
x = -1
