Question

in the figure of AOB is a straight line. find yhe mesure of LCOD​

Answer 1

Answer:

As AOB is a straight line,

<AOB = 180°

<AOC+<COD+<DOB = 180

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

3x = 120°

x = 40°

<COD = 2x-20

<COD = 60°

Answer 2

Step-by-step explanation:

AOC + COD + BOD = 180° [Linear Pair]

(x+20) + (2x-20) + 60 = 180°

3x + 60 = 180°

3x = 120°

x = 40°

COD = 2*40 - 20

= 60°
