Answer:
They are: area of sector and area of triangle
Step-by-step explanation:
Area of segment=area of sector - area of triangle
So we need both the area of sector and area of triangle to calculate for the area of a segment
The third option I believe

Answer:
Step-by-step explanation:
We would assume that triangle ABC is a right angled triangle. This means that we can apply Pythagoras theorem in determining the unknown side length.
For the case of the minimum side length, we would assume that the unknown length, L is one of the shorter legs of the triangle. By applying Pythagoras theorem, it becomes
11² = 9² + L²
L² = 121 - 81 = 40
L = √40 = 6.32
For the case of the maximum side length, we would assume that the unknown length, L is one of the hypotenuse of the triangle. By applying Pythagoras theorem, it becomes
L² = 9² + 11²
L² = 81 + 121 = 202
L = √202 = 14.21
The minimum side length is 6.32 and the maximum side length is 14.21
Ans is 8 and -1
8 + (-1) = 7
and
8 * (-1) = -8
