Which angle has a sine of −12 and a cosine of −3√2 ? A 7π6 B 4π3 C 5π6 D 5π3
1 answer:
Answer:
A. 7π/6.
Step-by-step explanation:
I think you mean a sine of -1/2 and cosine of -√3/2 ( the values in the question are not possible)
Angle π/6 has a sine of 1/2 and a cosine of √3/2 ( from the 30-60-90 triangle).
This angle must be in the third quadrant because the sin and cos are negative.
So the answer is π +π/6 = 7π/6.

Answer:
(–3, 0) and (1,0)
Step-by-step explanation:
The x-intercepts are where the curve crosses the x-axis. Your problem statement tells you ...
"crosses the x-axis at (negative 3, 0) and (1, 0)"
This means the x-intercepts are (-3, 0) and (1, 0).
