Question

Find the angle measure of angle E in Triangle DEF if angle D is 34 degrees & angle E is 117 degrees.

Answer 1

Answer:

        m∠E = 29°

Step-by-step explanation:

The sum of the measure of the interior angles in a triangle is 180°

m∠D + m∠E + m∠F = 180°

34°  + m∠E + 117° = 180°

     m∠E = 29°
