Question

in the figure OA and OB are opposite 1: if angle BOC= 75° , find angle AOC. 2: if angle AOC =110°, find angle BOC​

Answer 1

Answer:

the sum of all the angles on a line is equal to 180 degrees

Step-by-step explanation:

given AOC = 110°

we know

AOC + BOC =180°

so BOC = 180°- AOC

BOC= 70°

hope u understand

Answer 2

1. If angle BOC=75°,

angle AOC + angle BOC=180° [Linear pair]

=> angle AOC= 180°- angle BOC

=> angle AOC=180°-75°

.`. Angle AOC=105°

2. If angle AOC=110°,

Angle AOC + angle BOC=180° [Linear Pair]

=> angle BOC=180°-110°

.'. Angle BOC=70°

Hope this will help you.....
