d L AODnIn the given figure, if AOB is a straight line, tin52x +102

Answer»

As angle AOB is straight line so sum of angles is 180°.

x + 10 + 7x/2 - 5 + x/2 = 180°

3x/2 + 7x/2 + 5 = 180°

10x/2 = 180° - 5°

5x = 175°

x = 175/5

x = 35°

angle AOD = x +10 + 7x/2 - 5 = 35° + 5° + (7×35)/2

= 40° + 122.5°

= 162.5°
