Answer 1

To find the measure of angle a using the Triangle Sum Theorem, we need to add up the measures of all the angles in the triangle, which should equal 180 degrees.

So, 72° + 38° + 70° + a = 180°

Simplifying, we get:

180° = 180°

Therefore, angle a = 180° - (72° + 38° + 70°) = 180° - 180° = 0°

Therefore, the measure of angle a is 0°.
