The statement "m angle 1 + m angle 2 + m angle 3 = 180 degrees" is true if angles 1, 2, and 3 are the three interior angles of a triangle. In any triangle, the sum of the interior angles is always 180 degrees. If the angles are labeled as m angle 1, m angle 2, and m angle 3, then their measures must collectively equal 180 degrees regardless of their individual measures.

A right angle is 90 degrees and a 1/3 of 90 degrees equals 30 degrees
Let's call the two angles angle 1 and angle 2. We are given that angle 1 and angle 4 form a linear angle and that angle 2 and angle 4 form a linear angle. Because linear angles measure 180 degrees, we arrive at: m<1 + m<4 = 180 m<2 + m<4 = 180. By subtracting the second equation from the first, we get: m<1 - m<2 = 0. And finally: m<1 = m<2. Thus, angle 1 is congruent to angle 2.
If the measure of angle A is 60 degrees, angle A is acute.
50 Degrees
then m=30

It means "measure". So m<AVB is saying "the measure of Angle AVB is/= ? degrees".
