Question

Angle AOC and angle BOC forms a linear pair. If the difference between the two angle is 20°. Find the measure of these angles.

Answer 1

Step-by-step explanation:

hi,

AOC + BOC = 180° -------(1)

SINCE, AOC - BOC = 20°. ------- (2)

FROM (1) & (2)

2AOC = 200°

AOC = 100°

then,

BOC = 180°-AOC = 180°-100° = 80°

BOC =80°
