Answer:
(b) √55
Step-by-step explanation:
The right triangles in this geometry are all similar, so the ratio of long side to short side is the same:
y/5 = 11/y
y² = 55 . . . . . . multiply by 5y
y = √55 . . . . . take the square root
__
And x=4√5 by looking at ratios of short side to hypotenuse.
In matrix form, the system is

First find the eigenvalues of the coefficient matrix (call it
).


Find the corresponding eigenvector for each eigenvalue:



Then the system has general solution

or

Given that
and
, we have

so that the system has particular solution
