D) construction of the angle bisector.
So if you have a triangle that is not equilateral the perpendicular bisectors would not work so you need angle bisectors.
I have drawn a diagram
The green is the angle bisectors and the yellow the perpendicular bisectors.
You can see the problem straight away

Answer:
60 tickets for children were sold
Step-by-step explanation:
Let x be the number of sold children's tickets and let y be the number of adult tickets sold, then we can pose the following equations.
(i) Because 132 tickets were sold in total
(ii) because the total of $ obtained by sales was 931.20.
We must clear x. Then we substitute (i) in (ii)
60 tickets for children were sold
Answer:
Diameter = 24 mm
Step-by-step explanation:
Volume of a sphere is 4/3 π
First, we solve for radius:
2304π = 4/3π
Multiply both sides by 3
3(2304π) = 4π
Divide both sides by 4π
6912π/4π =
1728 =
Cuberoot both sides
= r
r= 12
Hence, the diameter would be: 2times the radius = 2*12= 24 mm
