Question

Find the value of a, b and c in the following figures:

Answer 1

Answer:

(I)

b= 72 ( vertically opposite angles)

a + 72 = 180 (linear pair)

a = 108

a = c. (vertically opposite angles)

c = 108.

(ii)

a = 44. (vertically opposite angles)

c + 44 + 63 = 180 (linear)

c + 107 = 180

c = 83

b + 44 = 180 (linear pair)

b = 136.
