You're looking for the answers to both X and Y, correct?<span />
There are two real roots (5 and -5) and 4 imaginary roots
Answer:
A
Step-by-step explanation:
Cosine is the ratio of "adjacent" to "hypotenuse"
With respect to the Angle E, the adjacent side is FE and the hypotenuse (always opposite side to 90 degree angle) is DE.
We are given DE = 26, but we need FE. We will solve for FE using Pythagorean Theorem, which tells us:
leg^2 + another leg^2 = hypotenuse^2
So, we will have:
10^2 + FE^2 = 26^2
Now, we solve for FE:

So,
Cos(E) = adj/hyp = 24/26
Correct answer is A
The answer to this is 2000...
hope this helps and HAGD!
Well if all angles are suppose to add up to 360 degrees you can the angles to see if the equal up to 360 degrees, 264+96=360.
