The reference angle is the smallest positive angle between the terminal ray and the x-axis. For a 2nd-Quadrant angle such as 150°, the reference angle is ...

  180° -x

_____

If your answer choice is really 180' -x, then the correct answer is "none of the above." 180' is 3°, since there are 60 minutes in a degree.

Cerrena [4.2K]

Answer:

a.2s b.43.6m

Step-by-step explanation:

h(t)=−4.9t2+19.6t+24

24m = inittial possition

-4.9 t2= -1/2 g t2

19.6t=  Vo t

as the initial velocity is positive, the ball is thrown up.

the maximum height of the ball is reached when the velocity is 0

V= Vo-gt=19.6m/s-9.8m/s2 t=0

t=19.6/9.8=2s

<u>it takes 2seconds for the ball to reach its maximum height</u>

h(t)=−4.9t2+19.6t+24

h(2)=-19.6m+39.2m+24=43.6m

<u>the maximum height of the ball is 43.6m</u>
