# In the adjoining figure, AOB is a straight line. Find the value of x. Hence, find,and .

X=32, =103°, COD =45°=32°

AOB is a straight line

Therefore, + COD + = 180°

(3x + 7)° + (2x - 19)° + x° = 180°

3x + 7° + 2x - 19° + x° = 180°

6x = 180° + 12°

6x = 192°

x = 32°

= (3x + 7)°

= 3×32° + 7 = 103°

COD = (2x - 19)°

= 2×32° – 19 = 45°

= x

= 32°
