Answer:
Step-by-step explanation:
x + 70 = 180 {Linear pair}
x = 180 - 70
x = 110
y + 82 = 180 {linear pair}
y = 180 -82
y = 98
x - 4 = 110 - 4 = 106
2y - 40 = 2*98 - 40
= 196 - 40
= 156
No, an obtuse triangle can only have one obtuse angle because when there are two angles greater than 90 the interrior angles become greater than 180°
