Answer:
2.) 7.8
Step-by-step explanation:
We can use Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 6^2 = c^2
25+36 = c^2
61 = c^2
Take the square root of each side
sqrt(61) = sqrt(c^2)
7.810249676 = c

Given

consider substituting
to get a proper quadratic equation,

Solve for
; we can factorize to get



Solve for
:

The first equation has no real solution, since
for all non-zero
. Proceeding with the second equation, we get

If we want to find all complex solutions, we take
so that the first equation above would have led us to
