Hình a: - Do x có góc ngoài = 110 nên: x = 180 - 110

x = 70

- Áp dụng tính chất tổng 4 góc của 1 tứ giác ta có:

y + 70 + 70 + 80 = 360độ

\(\Rightarrow\) y = 360 - (70 + 70 + 80)

\(\Rightarrow\) y = 360 - 220 = 140

Hình b + hình c làm tương tự nha bạn, riêng hình c có cái góc bỏ trống là góc vuông = 90độ á
