Help me please this is due in like 30 mnutes

Sin(30) = 1/2;

Cos(30) = sqrt(3)/2

Tan(60) = sqrt(3)

Step-by-step explanation:

Sin(30) = opposite/hypotenuse

Sin(30) = 7/14 = 1/2

Cos(30) = adjacent/hypotenuse

Cos(30) = 7sqrt(3)/14 = root(3)/2

sqrt: square root

Tan(60) = opposite/adjacent

Tan(60) = 7sqrt(3)/7 = sqrt(3)

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
