To find the measures of angles 1, 2, and 3 based on your description, it seems we need to use the relationships between the angles.

Let's denote the three angles as follows:

  • \( m\angle 1 = x \)
  • \( m\angle 2 = 40^\circ \)
  • \( m\angle 3 = 40^\circ \)

Finding \( m\angle 1 \)

From the information provided:

  • If \( \angle 1 \) is adjacent to \( \angle 2 \) and \( \angle 3 \) and forms a linear pair with one, we can sum angles around a point or along a line to find \( m\angle 1 \).

If \( \angle 1 \) is formed with the \( 85^\circ \) angle we need to consider if the provided \( 40^\circ \) angles are related to it. We can analyze based on the assumption that they probably form a triangle or are related in some manner.

Assuming \( \angle 1 \) and \( 40^\circ \) together with \( 85^\circ \) create an angle measure summing to \( 180^\circ \):

  1. Calculate \( m\angle 1 \):

\[ m\angle 1 + 40^\circ + 85^\circ = 180^\circ \] \[ m\angle 1 + 125^\circ = 180^\circ \] \[ m\angle 1 = 180^\circ - 125^\circ \] \[ m\angle 1 = 55^\circ \]

So, \( m\angle 1 = 55^\circ \).

Finding \( m\angle 2 \)

Since \( m\angle 2 = 40^\circ \), this value is as given and does not need further calculations.

Finding \( m\angle 3 \)

Similarly, since \( m\angle 3 = 40^\circ \), this value is also as given and does not need further calculations.

Summary of measures

  • \( m\angle 1 = 55^\circ \)
  • \( m\angle 2 = 40^\circ \)
  • \( m\angle 3 = 40^\circ \)

Final Answers

The measure of angle 1 is 55 degrees. The measure of angle 2 is 40 degrees. The measure of angle 3 is 40 degrees.
