Answer 1

Answer:

We know that on a straight line ,the sum of angles on one side is equal to 180°.

So,

(3x+7)°+(2x-19)°+x°=180°

3x+7+2x-19+x=180°

3x+2x+x+7-19=180°

6x-12=180°

6x=180°+12°

6x=192°

x=192°/6

[x=32°] answer///

Now ♪AOC=(3x+7)°

=3×32+7

=96+7

♪AOC=103°////)Answer

also,♪COD=(2x-19)°

=2×32-19

=64-19

♪COD =45°answer////

and ♪BOD=32°answer ///)

Hence,♪BOD=32°,√COD=45° and ♪AOC=103° .ANSWER ///
