⇒ (let h=0 it is given)
⇒
⇒
⇒ t=8.96≈9 s (the other root is negative)
Hence, rocket will take 9 s to hit the ground after launched.
Answer:

Step-by-step explanation:
From the figure attached,
Measure of an angle = 20°
Measure of the opposite side = x
Measure of the adjacent side = 12
By applying tangent rule in the given right triangle,
tan(20°) = 


Therefore, equation to get the value of 'x' will be,
