Question

please give me a answer step by step ​

Answer 1

Answer:

Name the points

then <EAO = <FBO = 120°

<AOB = <COD = x°

To find is x°

<EAB = <FBA = 180°

<BAO = <EAB - <EAO

<BAO = 180 - 120

<BAO = 60°

<BAO = <ABO = 60°

∆AOB = 180°

<BAO + <ABO + <AOB = 180°

60 + 60 + <AOB = 180

120 + <AOB = 180

<AOB= 180 - 120

<AOB = 60°

<AOB = <COD = x

<AOB = 60°

<COD = 60°

x = 60°

Hope my answer is correct
