heeya plzzz give the answer fast . and who will give me correct ans with solution will be marked as brainliest answer. give the answer with proper language. please fast

Answer 1

Hello Mate!

I am using "<" as angle symbol.

<COA + <C + <OAC = 180° ( Angle Sum property )

40° + 80° + <OAC = 180°

<OAC = 180° - 120°

<OAC = 60°

<OAC + x° = 180° ( Linear pair )

60° + x° = 180°

x = 120°

<BOD + <OBD + <D = 180°

<BOD = <COA ( Vertically opposite angle )

40° + 70° + <OBD = 180°

<OBD = 180° - 110°

<OBD = 70°

<OBD + y° = 180°

y = 180° - 70° = 110°

Answer : x = 120° ; y = 110°

Have great future ahead!

Answer 2

<COA + <C + <OAC = 180° ( Angle Sum property )

40° + 80° + <OAC = 180°

<OAC = 180° - 120°

<OAC = 60°

<OAC + x° = 180° ( Linear pair )

60° + x° = 180°

x = 120°

<BOD + <OBD + <D = 180°

<BOD = <COA ( Vertically opposite angle )

40° + 70° + <OBD = 180°

<OBD = 180° - 110°

<OBD = 70°

<OBD + y° = 180°

y = 180° - 70° = 110°

Answer : x = 120° ; y = 110
