Question

in the adjoining figure ab is a straight line find the value of x find angle AOC, angle COD,and angle BOD

Answer 1

Heya!!Here is your answer friend ⤵⤵
↔↔↔↔↔↔↔↔↔↔↔↔↔

➡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 ✌✌

Answer 2

Given :  AB is a straight line .

To Find  : the value of x

∠AOC , ∠COD, ∠DOB

Solution:

∠AOC + ∠COD + ∠DOB = 180°   ( as AB is straight LIne)

∠AOC = 3x + 7

∠COD = 2x - 19

∠DOB = x

∠AOC + ∠COD + ∠DOB = 180°  

=> 3x + 7 + 2x - 19 + x  = 180°

=> 6x  - 12 = 180°

=>  6x   = 192°

=> x = 32

∠DOB = 32°

∠AOC = 3x + 7  = 3(32) + 7 = 103°

∠COD = 2x -19  = 2(32) -19 = 45°
