Explore: Compare the measures of $\"\"$ with $\"\"$ .

Plan: To compare the angle measures use the properties and theorems of real numbers. $\"\"$

Solve: Compare $\"\"$ .

By the exterior angle theorem $\"\"$ . Since the angle measures are positive

numbers and from the definition of inequality, $\"\"$ .

Compare $\"\"$ .

Again, by the exterior angle theorem, $\"\"$ .

Since from the definition of inequality, $\"\"$ . $\"\"$

Check: $\"\"$ is greater than the measures of $\"\"$ . Thus, $\"\"$ is the greastest measure.
