Is this a question or a comment? Sorry I'm confuse...
Answer:
they are vertical angles
Step-by-step explanation:
just learned about this
The answer is 20 since 1/5 of 20 is 4, and 20 + 4 = 24.
It hits the ground at h=0
0=-16t^2-16t+96
undistribute -16
0=-16(t^2+t-6)
factor
0=-16(t-2)(t+3)
set to zero
0=t-2
2=t
t+3=0
t=-3, nope, we can't have negative time
at t=2, or 2 seconds
