The horizontal distance to the control tower is approximately 18506.83m
Data;
- distance from the ground = 3900m
- angle of elevation = 11.4 degrees
- horizontal distance = ?
<h3>Trigonometric Ratio</h3>
To solve this problem, we need to use trigonometric ratio SOHCAHTOA.
In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.

Step-by-step explanation:

Answer:
$837.5
Step-by-step explanation:
Step one:
given data
He makes a guaranteed salary of $400 per week
Commision on top of his base salary equal to 25% of his total sales for the week
Required
His total salary when he made sales of 25%
Step two
let us solve for 25% of $1750 made
=25/100*$1750
=0.25*$1750
=$437.5
Hence his total payment for the week will be
=$400+$437.5
=$837.5
Also, if the sales is $x his pay would be
let y be his pay
y=0.25x+400
The answer is C. 98.47
