ANSWER
The value of x is

EXPLANATION
We want to solve the equation,

The first step is to add 4 to both sides of the equation to obtain,

We simplify the right hand side to obtain,

We now square both sides of the equation to obtain,

This simplifies to

We solve for x to obtain,

This implies that,
Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
