Answer:
D. 158.4 km²
Step-by-step explanation:
Area of sector = θ/360 * πr²
Where,
θ = 150°
r = 11 km
Substitute
Area = 150/360 * π * 11²
Area = 158.38863 ≈ 158.4 km² (nearest tenth)

Step-by-step explanation:
Answer:
(A), (D), and (E)
Step-by-step explanation:
In a quadratic function, the solutions are always on the x-axis, which means that it can be another word for x-intercept. Also, a zero and a root are the same thing, and they are both x-intercepts. Hope this helps!
Answer: 63
Step-by-step explanation: 21+21+21
Answer:
30°
Step-by-step explanation:
Let the measure of the missing angle be x°
Therefore, by interior angle sum postulate of a triangle:
x + 60° + 90° = 180°
x + 150° = 180°
x = 180° - 150°
x = 30°
Thus the measure of the missing angle is 30°.
