Answer:
Correct answer is 54.82 ft.
Step-by-step explanation:
First of all, let us label the diagram and do the construction as per the attached answer image.
Let us consider 
:
Let side AB = d ft and let side BC = x ft
We need to find AB to find the shortest distance across the river.
Using trigonometric identity of tangent:
Now, let us have a look at another right angled triangle ABD:
Let us consider :
side AB = d ft and side BD = x+75 ft
Using trigonometric identity of tangent:
Correct answer is 54.82 ft.
Factor 6x^5−18x^3+54x^2
6x^5−18x^3+54x^2
=6x^2(x^3−3x+9)
Answer:
6x^2(x^3−3x+9)
Answer:
y=-1/3x+4/3
Step-by-step explanation:
y-y1=m(x-x1) m=1/3 x1=3 y1=2
y-2=1/3(x-2)
y-2=-1/3x-2/3
y=-1/3x+4/3
Side of the square computer screen = 21 inches
It is important to minutely read the details that are already given in the question. the most important information that is given in the question is that the computer screen ia square. Based on this information the answer to the question can be easily deduced.
Then
Area of the computer screen = (Side)^2
= (21)^2 inches square
= 441 inches^2
So the area of the square computer screen is 441 square inches. i hope the procedure is clear enough for you to understand.
