Question

in the given figure, AOB is a straight line. find the measurement of angle COD.​

Answer 1

Answer:

20 degree

Step-by-step explanation:

Answer 2

Answer:

∠COD = 60°

Step-by-step explanation:

∠AOC + ∠COD + ∠DOB = 180°

=> (x + 20) + (2x - 20) + 60 = 180

=> x + 20 + 2x - 20 + 60 = 180

=> 3x = 180 - 60

=> x = 120/3

=> x = 40

Therefore, we have found out the value of "x"

Now, ∠COD = (2x - 20)° = (2 x 40 - 20)° = (80 - 20)° = 60°
