Answer:
Angle of Depression and Angle of Elevation
One application of the trigonometric ratios is to find lengths that you cannot measure. Very frequently, angles of depression and elevation are used in these types of problems.
Angle of Depression: The angle measured down from the horizon or a horizontal line.
Angle of Elevation: The angle measured up from the horizon or a horizontal line.
What if you placed a ladder 10 feet from a haymow whose floor is 20 feet from the ground? How tall would the ladder need to be to reach the haymow's floor if it forms a 30∘ angle with the ground?
Option D:
is the equation of line
Explanation:
The equation of the line is perpendicular to the line
and that passes through the point 
We need to determine the equation of the line.
First, let us determine the slope of the equation.
Since, the equation is perpendicular to the line
, the slope is 
Since, the lines are perpendicular, we have,

Now, we shall substitute the slope
and the point
in the slope - point formula, we have,



Hence, writing this equation in slope - intercept form, we have,


Thus, the equation of the line is 
Therefore, Option D is the correct answer.
Answer:
Step-by-step explanation:
Answer:
80 I'm pretty sure
Step-by-step explanation:
Value + value = 8379.70
249.99x + 329.99*30-329.99x = 8379.70
-80x + 9899.70 = 8379.70
-80x = -1520.00
x = 19 (number of the cheaper mowers sold)
30-x = 11 (number of more expensive mowers sold)
