The measure of angle F is 92 degrees.

The angles in a triangle

The sum of the angles that are in  a triangle is = 180 degrees.

One angle = 31°

The second angle = 57°

The value of F is unknown.

When we apply this law we have:

31° + 57° + F = 180°

F = 180-31-57

F = 92°

Therefore the measure of angle F is = 92°
