Answer:
So these two equation can be related by identity 
Step-by-step explanation:
We have given equation 
And 
We know the algebraic identity 
From this identity
can be written as (x+1) (x-1)
And using same identity
can be written as 
So these two equation can be related by identity 
Answer: 192
Step-by-step explanation:
(22.14-19.58)x75
Set up a right triangle
The base will be 2,500 feet and the angle where the hypotenuse meets the base will be 4 degrees
The height is your x value,
tan4=x/2,500
Multiply both sides by 2500
2500tan4=x
x=174.817
The answer is B
