(a)

\

Let x is the m numbers of the angle $\"\"$ that means $\"\"$ and y is the m numbers of the another angle $\"\"$ that means $\"\"$ .

\

The sum of the measure of angles $\"\"$ is $\"\"$ , so the equation form is $\"\"$ .

\

The measure of angle $\"\"$ is $\"\"$ greater than the measure of angle $\"\"$ , so the equation form is $\"\"$ .

\

$\"\"$

\

(b)

\

The system of equations are $\"\"$ .

\

Equation 1: $\"\"$

\

Equation 2: $\"\"$ .

\

The second equation is already solved for y.

\

The value of $\"\"$ substitute in the first equation, $\"\"$ .

\
