Question

in a trapezium if AB||CD find value of x ,if AO=x+5,OC=x+3,OD=x-2 and OB=x-1

Answer 1

Since ABIICD In trap. ABCD, So we can prove triangle AOB similar to triangle COD using (A.A Similarity),

we now get AO/CO= BO/DO (C.P.S.T)

On substituting the values of AO, OC, DO and BO we get,

x=7

Hope so i am right !!!!
