Solution Steps

Step 1: Identify the relationship between angles 1 and 2

Angles 1 and 2 are formed when a transversal intersects two parallel lines. They are same-side exterior angles.

Step 2: State the property of same-side exterior angles

Same-side exterior angles are supplementary, meaning their sum is 180 degrees.

Step 3: Calculate the measure of angle 2

Since angles 1 and 2 are supplementary, and angle 1 measures 105 degrees, angle 2 measures 180 - 105 = 75 degrees.

Final Answer

75
