Ответ:
x = 40 , y = 100
Step-by-step explanation:
3x - 20 and 2x are same- side interior angles and sum to 180° , that is
3x - 20 + 2x = 180
5x - 20 = 180 ( add 20 to both sides )
5x = 200 ( divide both sides by 5 )
x = 40 and 2x = 2 × 40 = 80
2x + y are adjacent angles on a straight line and sum to 180° , then
y + 80 = 180 ( subtract 80 from both sides )
y = 100
