The complementary angle is 72
Step-by-step explanation:
Complementary angles add to 90 degrees
Let x be the complementary angle
x+18 = 90
Subtract 18 from each side
x = 90-18
x = 72
For this case we have that the equation that describes the height is:

Where,
v: initial speed
c: initial height
Substituting values we have:

Then, to find the time, we use the quadratic formula:

Substituting values we have:

Rewriting:



We discard the negative root because we want to find the time.
We have then:
