Step-by-step explanation:
The value of x is 7.
Step-by-step explanation:
Given information: AB || DC.
In triangle AOB and COD,
\angle AOB=\angle COD∠AOB=∠COD (Vertically opposite angles)
\angle OBA=\angle ODC∠OBA=∠ODC (Alternate interior angles)
\angle OAB=\angle OCD∠OAB=∠OCD (Alternate interior angles)
By AA rule of similarity,
\triangle AOB\sim\triangle COD△AOB∼△COD
The corresponding sides of two similar triangles are proportional.
\frac{OA}{OC}=\frac{OB}{OD}
