Answer: About 3.06
Step-by-step explanation:
We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.
Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.
cos(θ) =
cos(40) =
0.766 ≈
3.06 ≈ x
x ≈ 3.06
If an expression is the difference of two squares, it will follow this format:
where a and b are integers or variables.
1)
Since the expression follows the format, it's a DoTS.
2) Since the binomial has an addition sign, it isn't a DoTS.
3)
The second term isn't an integer, so the expression isn't a DoTS.
4)
Since the expression follows the format, it's a DoTS.
Therefore, the first and fourth expressions are differences of two squares.
