60o

Bond angle, in water the H-O-H angle is 105o, in carbon dioxide O=C=O angle is 180o.
30 degrees.
150
O=C=O is the structure and it is linear. So the bond angle is 180o
180
Remember the sum of the 3 angles of a triangle = 180degrees Let angle 1 = x angle 2 = 2x angle 3 = x-20 Sum = x + 2x + x - 20 =180o 4x - 20 = 180o 4x = 200o x = 50o 2x = 100 o x - 20 = 30o angle 1 = 50o angle 2 = 100 o angle 3 = 30o
