the given problem can be exemplified in the following diagram:
The slope is defined as the tangent of the angle, therefore the slope is:

Therefore, the slope is 1.96.
When the rocket has travelled 66 yards, we have the following situation:
To determine the value of the height "y" we can use the function tangent since this function is defined as:

Replacing the known values:

Multiplying both sides by 66 we get:

Solving the operations:

Therefore, the height is 129.7 yards.
When the rocket is at a height of 308 yards, we have the following situation:
we can use the tangent function. Replacing the known values we get:

Multiplying both sides by "x":

Dividing both sides by tan 1.1:

Solving we get:
