Question

7. Find the value of x in the following figures. ​

Answer 1

a) => x = 32 [∵They are a pair of vertically opposite angles]

b) => x + 43 = 180 [∵They are a pair of angles in linear pair]

   or, x = 137

c) => (6x+19) + 83 = 180 [∵They are a pair of angles in linear pair]

   or, 6x + 102 = 180

   or, 6x = 78

   or, x = 13

d) => (3x+2) = 62  [∵They are a pair of vertically opposite angles]

    or, 3x = 60

     or, x = 20
