Answer 1

Hi friend
-------------
Your answer
-------------------

HERE,
---------

IN ∆AOB, WE HAVE,
------------------------------

OA = OB [ RADIUS OF THE SAME CIRCLE]

THEN, ANGLE OBA= ANGLE OAB = 20°
SO,
ANGLE AOB = 180° - (20+20)° = 180° - 40°= 140°

SIMILARLY
----------------

IN ∆AOC, WE HAVE,
------------------------------

AO = OC [ RADIUS OF THE SAME CIRCLE]
THEN, ANGLE OCA = ANGLE OAC = 30°
SO,
ANGLE AOC = 180°- (30+30)° = 180°- 60° = 120°

NOW,
-------
EXTERIOR ANGLE BOC = X = 360° - (ANGLE AOB+ ANGLE AOC)
= 360° - (140°+ 120°)
= 360° - 260°
= 100°

THEREFORE, X = 100°

HOPE IT HELPS
