Ответ:
x=36.1
supplementary angle = 143.9 degrees
Step-by-step explanation:
angle: x
supplementary angle: 180-x
x = (180-x)-107.8
2x = 72.2
x = 36.1 degrees
180-x = 143.9 degrees
supplementary angle = 143.9 degrees
x measures 107.8 less than 180-x
x=180-x-107.8
x=72.2-x
Add x to both sides
2x=72.2
Divide both sides by 2
x=36.1
hope this helps, I just solved this so probably should get it fact checked.
