Answer 1

Answer:

angle ODC = 10°

Step-by-step explanation:

Given,

Angle oab = 65°

angle oba = 45°

angle ocd = 100 °

Then,

angle aob = 180 ° - (angle oab + oba ) sum of all angles of a ∆ is 180°

180° - (45 + 65 )°

( 180-110)°

70 °

angle cod = angle aob ( alternate angle )

angle cod = 70 °

Now ,

angle odc = 180° - ( aob + ocd )°

180° - (100 + 70)°

(180 -170)°

10°
