Question

in the given figure, find the value of x . what is the measure of angle COD​

Answer 1

Answer:

4x + 3x + 20 + 2x - 5 + x - 5 = 180

10x + 10 = 180

x + 1 = 18

x = 18 - 1 = 17

x = 17°

For COD, 3x + 20 = 3× 17 + 20 = 71

Answer 2

Answer:

The total angle at point O is 360°

So,

(3x+20)° + 4x° + (x-5)° + (2x-5)° = 360°

10x + 10 = 360

10x = 360 - 10

x = 350/10 = 35°

x = 35°

Using that, angle COD

is 3x+20 = 3(35)+20 = 105+20 = 125°

<COD = 125°
