Answer 2

Answer:

Step-by-step explanation:

Angle BOD = 63°

TO FIND = ANGLE BOC

GIVEN = AB and CD are straight lines intersecting at O.

NOW,

Since, It is given that :-

Line CD is straight.

This means that the sum of the angles on the line is equal to 180°

{LINEAR PAIR AXIOM}

So,

Angle BOD + Angle BOC = 180°

{LINEAR PAIR AXIOM}

So,

Angle BOC = 180 - Angle BOD

Or,

Angle BOC = 180 - 63 = 117°
