Question

if rayOC stands on line AB,
angle BOC=120 degree
find reflex angle AOC​

Answer 1

Answer:

$the \: sum \: of \: two \: adjacent \: angles \: is \: 180 \: degrees \: then \: they \: are \: a \: linear \: paiir$

Answer 2

Answer:

240°

Step-by-step explanation:

angle BOC =120°

Now complete angle(BON) =360°

hence angle BOB = angleBOC + angleCOB

360°= 120° + angle COB

hence, 360 - 120° = angle COB

angle COB. = 240°

hence, reflex angle is 240°
