The measure of the additional angle needed for Stephanie to get out is 50°.

To answer the question, we need to know what angles are

What are angles?

Angles are a measure of rotation.

Since Stephanie needs to rotate the door 170° for her to pass through but then rotates it 105° and gets stuck, her friend then helps her push the door another 15°, but still not far enough.

The additional angle needed

Let x be the additional angle needed.

So, x + 105° + 15° = 170°

x + 120° = 170°

x = 170° - 120°

x = 50°

So, the measure of the additional angle needed for Stephanie to get out is 50°.
