If you have a triangle and the first two measures are 102 and 28, what is the missing measure in the triangle

50°

Explanation:

Given angles;

Angle 1 = 102°

Angle 2 = 28°

Unknown:

Missing angle  = ?

Solution:

The sum of the three angles in a triangle is 180°

  Angle 1 + Angle 2 + missing angle  = 180°

       102 + 28 + missing angle  = 180

               missing angle = 180 - 130

                missing angle  = 50°
