The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is

-------------------------------
The range is

since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.
Simplify the right hand side:

Expand the left hand side:

Subtract 2x from both sides:

Divide both sides by 4:

Answer:
h = 1.403733341286
Step-by-step explanation:

the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.
Then

Then

Then

For l = 6 and θ = 40 :

= 6-6cos(40)
= 1.403733341286
