please answer me Please Answer​

Answer 1

Answer:

Step-by-step explanation:

In the given quadrilateral :-

: AB || DC .......(given)

: OD= X .......(given)

: OB= X-3 .......(given)

: OC= X-5 .......(given)

: OA= 3X-19 .......(given)

: Consider Triangle ADB and Triangle BCD :-

: Construct :- EF || AB || DC which is passing through 'O'.

: In Triangle ADB and Triangle BCD :-

: DO/OB = CO/OA

: X/X-3 = X-5/3X-19

: After solving the equation :-

: X = (-1) , X = (15)
