Answer:
71.1° and 108.9°
Explanation:
- An angle measures 37.8° less than the measure of its supplementary angle. what is the measure of each angle?
Supplementary angles are those angles that sum up to 180°
x + x + 37.8 = 180
2x = 180 - 37.8
2x = 142.2
x = 142.2 : 2
x = 71.1 (smaller angle)
71.1 + 37.8 = 108.9 (larger angle)
----------------------------
Check
71.1 + 108.9 = 180
108.9 - 71.1 = 37.8
