Question

In adjoining fig. find the value of x and hence determine the values of angle AOC , angle COD and angle BOD.

Answer 1

Answer:

➡Given that A B is a straight line,

Using the property , the sum of angles on a straight line =180

= 3x +7 +2x -19+ x = 180

= 6x= 180+12

=6x = 192

= x= 192/6

= 32

Hence , the angles are

x=32

3x+7 = 96+7

= 103

2x-19= 64-19

=45

➡Hence angles are 45, 103 and 32.

Hope it helps you ✌✌
