Use the trig ratio which
gives you the most information. Here we have opposite and hypotenuse
relative to angle x, so think sin( x ) = 14.1 / 27.9<span>Now we want to solve for x, but x is stuck inside the sine function
So how do we do this?
We can 'undo' the sine function by using the inverse sine. apply the inverse Sin to both sides of the equation.
sin^-1 ( sin(x) ) = sin^-1 ( 14.1 / 27.9)
the left side 'cancels' , leaving you with x
x = sin^-1 ( 14.1 / 27.9)</span><span>Now you need a calculator.
Make sure you are in degree mode.
Calculators can give you answer in radian or degree.
If you get a decimal answer, you are probably in radian mode.
Round up if you want nearest hundredth
30.3563 ≈ 30.36
Round up again if you want nearest tenth
30.36 ≈ 30.4
Hope this helps! :)

Answer: $553.20
Step by step explanation: Since they took the price down 29% multiply the price by 1.29 to add the 29 percent back to the total amount. 428.84 * 1.29 = 553.20
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
