The OC and OD beams share the AOB angle so that the BOD angle is 5/18 AOB and AOC 10/21
June 24, 2021 | education
| Let’s take a look at the figure to solve it.
The value of the angle AOB = 180, since the angle is unfolded.
BOD angle = (5/15) * AOB = 5/18 * 180 = 50.
Also the angle BOD = (10/21) * AOC.
AOC = (21/10) * BOD = (21/10) * 50 = 110.
Then the angle COD = 180 – 110 – 50 = 20.
Answer: BOD = 50.
AOC = 110.
COD = 20.
