(3x + 10) + (4x - 26) = 180°
⇒ 7x - 16 = 180°
⇒ 7x = 180 + 16
⇒ 7x = 196
⇒ x = 196/7
⇒ x = 28°
angle BOC (4x - 26)
⇒ 4(28) - 26
⇒ 86°

Step-by-step explanation:
a + b = 180 ° 【 linear pair 】
( 3x + 10° ) + ( 4x - 26° ) = 180°
7x - 16° = 180°
180° - 16° = 7x
196° / 7 = X
28° = X
3×28° + 10 = 94° [ angle AOC ]
4×28-26 = 86 ° [ angle BOC ]
So , the answer of this question is option (b) 86°
