Analyze the problem situation(s) described below. Organize and record your work for each of the following tasks. Using precise mathematical language, justify and explain each solution process.

Given:

The sum of the angles in a hexagon is 720°.

To find:

(a) Equation to solve the value of x.

(b) The value of x.

(c) The measure of angle C.

Solution:

(a)

We have,

The sum of the angles in a hexagon is 720°.

Therefore, the required equation is .

(b)

On solving the above equation, we get

Divide both sides by 3.

Therefore, the value of x is 42.29.

(c)

We need to find the measure of angle C.

Therefore, the measure of angle C is 126.87 degrees.
