Question

in a adjoining figure , if AOB is a straight line, if angle AOC:COD:DOB=2:3:4 find the angles AOC, COD,DOB​

Answer 1

Answer:

AOC=40⁰, COD=60⁰, DOB=80°

Step-by-step explanation:

2x+3x+4x=9x=180⁰ i.e. straight angle

x = 180/9 = 20

AOC = 20 x 2 = 40⁰

COD = 20 x 3 = 60⁰

DOB = 20 x 4 = 80⁰
