Question

In the figure, lines AB and CD Intersect at O if < AOL = 180º , find the value of A,B,C

Answer 1

Step-by-step explanation:

2c = a ( vertically opp. angles)

2c + 3b = 180

108 + a + c = 180

a + c = 72

replacing a,

2c + c = 72

3c = 72

c = 24

2c = a

a = 48

2c + 3b = 180

3b = 180 - 48

3b = 132

b = 44
