Distance of the person from the building (x)
tan 24 = 20/x => x = 20/tan 24 = 44.92 ft
The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.
Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft
Answer:
The current that produces maximum power is 3A
Step-by-step explanation:
Given
Required [Missing from the question]
The current that produces maximum power
First, we represent the function in standard form
Open bracket
The maximum value of c is:
Where:
By comparison:
So, we have:
D) perpendicular!
A perpendicular's definition is: a straight line at an angle of 90° to a given line, plane, or surface.
And if you mark them on a graph you could see these two are opposite of each other.
Question
15 is the same as the product of 3 and a number. Which equation models this sentence?
15=3x
15=x-3
15=3+x
15=x divided by 3
Answer:
<h2>
15=3x</h2>
Step-by-step explanation:
15 = 3x
x = 15 : 3
x = 5
.........................
check
15 = 3 * 5
15 = 15
the answer is good
