01

Step 1. Given Information.

The figure is shown below.

Step 2. Concept used.

If two angles formed at the intersection point of two lines are opposite to each other, then the measures of the angles, called as vertical angles, are equal.

03

Step 3. Calculation.

鈭�1has the same measure as its opposite angle. Since the angle opposite to 鈭�1 has a measure of 65掳, write,

m鈭�1=65掳

04
