if we put n as the number of sides in a regular polygon, the formula to find the measure of each angle is

so the answer will be

they each measures 144 degrees
good luck
it gives you the formula, so all you have to do is plug in the coordinates

Answer:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Step-by-step explanation:
For this case we have the function of the height in terms of the time givenby:

And we want to known when the rockect hit the ground and for this case we need to solve the equation 

And as we can see we have a quadratic equation like this one:

Where: 
And the general solutions are given by:

If we replace the values that we have we got:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
