<h3>What is ammonia?</h3>
Ammonia is defined as a gas compound that is made up of nitrogen and oxygen in the ratio of 1:3 respectively.
The industrial and modern method constructed by Engineers for ammonia production is called steam reforming.
The natural resources used for industrial production of ammonia can be gotten from natural gas such as methane.
To make profit, natural products are used which costs less to acquire but will lead to the production of large ammonia quantity.

Answer:
89.1° or -1.4°
Step-by-step explanation:
1. Location:
You are on the Mont-Saint-Jean escarpment, near the Belgian town of Waterloo.
The French troops are about 50 m below you and 1.2 km distant.
2. Finding the firing angle
Data:
R = 1200 m
u = 600 m/s
h = -50 m (the height of the target)
a = 9.8 m/s²
We have two conditions.
Horizontal distance
(1) 1200 = 600t cosθ
Vertical distance
(2) -50 = 600t sinθ - 4.9t²
Divide each side of (1) by 600cosθ.

Substitute (3) into (2)

Recall that
(5) sec²θ = 1/cos²θ = tan²θ + 1
Substitute (5) into (4)

Set up a quadratic equation

Solve for θ
Use the quadratic formula.
tanθ = 61.249 or -0.025
θ = arctan(61.249) = 89.1° or
θ = arctan(-0.025) = -1.4°
