Respuesta :

55 because alternate interior angles are congruent and then you can do some basic algebra

Answer: angle 5 is 55 degrees.

Start by solving for angle 2 by using the linear pair rule: all linear angles sum to 180

125 + angle 2 = 180

angle 2 = 55

Now, we know that line l and line m are parallel. If we look at these two lines plus the left side of the triangle, we can see it forms a z shape. This means angle 2 and angle 5 are alternate exterior angles. This means they are congruent.
