Question

In fig 1.2 , two straight line pq and rs intersect at o .if pot = 75. find the value of a , b,c.​

Answer 1

Answer:

take RS line ,

4b+75+b = 180

5b = 180-75=105

b= 105/5 = 21

now take PQ line,

75+b+a =180

75+21+a =180

a = 180-75-21 =84

now again take RS line for uper angle

2c+a = 180

2c = 180-84=96

c = 48

hence,

a=84

b=21

c=48
