Question

find its value by the figure.........​

Answer 1

angle 1 = angle3 .............(vertically opposite angle)

angle 3 = 70°

angle 1 + angle 2 = 180° ....... (linear pair)

70 + angle 2 =180°

angle 2 = 110°

angle 2 = angle 4 .......(vertically opposite angle)

angle 4 = 110°

angle 4 = angle 8 .....(corresponding angle)

angle 8 = 110°

angle 8 = angle 6 ......(vertically opposite angle)

angle 6 = 110°

angle 6 + angle 5 = 180 .....(linear pair)

110° + angle 5 = 180°

angle 5 = 70°

angle 5 = angle 7 .......(vertically opposite angle)

angle 7 = 70°
