Question

Q1
in the given figure, two straight lines AB and
CD intersect each other at o. If angle coe = 70°
find the value of a, b andC.​

Answer 1

Answer:

CO and EO stand on AB, therefore

4b + 70 + b = 180

 5b = 110

 b = 22

Also, a = 4b (V.O.A)

a = 4  22 = 88

Now a + 2c = 180

88 + 2c = 180  2c = 92

 c = 46

Hence a = 88, b = 22, c = 46
