The value of the exterior angle is the sum of the angles opposite. This is an equilateral triangle, so all angles are equal to 60 degrees.

60 + 60 = 120

So angle DAB is 120 degrees.

Triangle DAB's angle measurement add up to 180 degrees

Since it is an equilateral triangle, each angle is the same measurements, or 60 degrees

Angle DAC is a straight line, and has a total measurement = 180 degrees

180 - 60 = 120

Angle DAB = 120 degrees


Hope this helps
