13. In the given figure, if angle AOC + angle BOC + angel BOD = 338°, find all the four angles
Answers
Step-by-step explanation:
We know that
Sum of all angles is 360
angle AOC+ angle BOC+ angle BOD + angle AOD = 360
338 + angle AOD = 360
Angle AOD = 360-338
Angle AOD = 22
Angle AOD = angle BOC
Because they are vertically opposite angles
They are equal to 22
And
Angle BOC + angle BOD = 180
Because linear pair...sum of those angles will be 180
22+angle BOD = 180
Angle BOD = 180-22
Angle BOD = 158
Angle BOD = Angle AOC = 158
Because vertically opposite angles are equal...
We got all the angles...
Angle AOC = 158
Angle BOC = 22
Angle AOD = 22
Angle BOD = 158
Answer:
angle aoc +angle boc = 180⁰ by linear angle property
then, 180+ angle bod = 338⁰
bod = 338-180 = 158⁰
bod + boc= 180
180- 158 = boc
22⁰ = boc
boc = aod = 22⁰ by opposite angle of intersecting lines
and
bod = aoc = 158⁰
