Answer:
Yes
Step-by-step explanation:
Tan = sin / cos
If sin is negative, ans cos is negative, then tangent is positive.
Tan= (-)/(-) = (+)
I believe 20 is your answer. Tell me if I’m wrong.
Answer:
that anzwer will be (9) ok
We use direct proportionality:
360⁰......Pi×R² (full circle)
120⁰.......x
x=120×pi×R²/360=pi×R²/3
x=pi×4²/3=16.76mi²
A=3×pi cm², for an angle of 2×pi/3=120⁰
In a similar way we compute the area of the full circle:
360.........x
120..........3×pi
x=3×pi×360/120=9×pi=3²×pi.
Thus the radius is 3cm.
The numbers are a squence.
