Answer:5/half’s
I don’t have an explanation but I think it’s that
The maximum height is 144 feet.
The maximum height is the y-coordinate of the vertex. To find the vertex, we first use x = -b/2a. For our information, that is x=-64/2(-16) = -64/-32 = 2.
Now we substitute this into the equation:
y = -16(2²) + 64(2) + 80 = -64 + 128 + 80 = 144
12 times 2 + 9 times 2 = 24 + 18 = 42 divided by 16 = 2.625
A triangles is 180 degrees. 100+50=150.
180-150=30
X=30
