Allen's claim that we do not have enough information to solve for angle 1 is incorrect
<h3>How to calculate the measure of angle 1</h3>
Given that:
Angle 2 = 110 degrees
Angle 1 and angle 2, are the only angles on the straight line.
So, we have:

Substitute 110 for angle 2

Subtract 110 from both sides

The measure of angle 1 is 70 degrees.
So, we can conclude that Allen's claim is incorrect
