Question

12. Find the value of x and y​

Answer 1

Answer:

y = 80° ( vertically opposite angles)

50 + 80 + x = 180°

130+ x = 180 °

x = 180-130

x = 50°

Answer 2

Answer:

y=80° {vertically opposite}

x+50+y=180 {the sum of angles of the triangle is 180°}

x+50+80=180

x+130=180

x=180-130

x=50
