Question

Pls answer this question

Answer 1

Answer:

Step-by-step explanation:

In triangle AOB and COD

Angle O is common

Angle D=Angle B = 60*

Therefore by    

                       AA similarity rule

Triangle AOB¬ Triangle COD

Therefore

               AB/CD=AO/CO=OB/OD   [cpst]

OB/OD=AB/CD

x / b+x = a / c

CROSS MULTIPLY b+x

Therefore

x = [b+x]a / c
