$\"\"$

If one angle of a triangle has a greater measure than another angle, then the side opposite the greater angle is longer than the side opposite the lesser angle.

$\"\"$ (Angle sum theorem)

$\"\"$ (Substitute angles)

$\"\"$ (Add: $\"\"$ )

$\"\"$ (Subtract 140 from each side)

Since measure of $\"\"$ is greater than the measure of $\"\"$ , the length of $\"\"$ is greater than the length of $\"\"$ . $\"\"$

The measure of $\"\"$ is greater than the measure of $\"\"$ , the length of $\"\"$ is greater than the length of $\"\"$ .
