Question

The measure of angle 1 is 30°, and the measure of angle 2 is 110°. A triangle has angles 1, 2, 3. The exterior angle to angle 3 is 4. What is the measure of angle 4? 40° 80° 140° 220°

Answer 1

Answer:

Angle 4 is 140 because angle 3 is 40 interior angles must add to 180 which means 180-110-30 = the missing interior angle. Acute plus obtuse = 180 so 180-40 = 140
