Answer:
(I)
the answer in x=3
Step-by-step explanation:
By basic proportionality theorem
AD/DB=AE/x
6/3=9/x
6x=9x3
6x=18
x=18/6
x=3
(ii) refer the image
hope this helps you

Answer:
In a triangle, according to basic propertional theorem, a line which is parallel to the third side of the triangle , can divide the other two sides in the same ratio.
(i) DE || BC
Hence ,
AD/DB = AE/EC [The above Theorem]
→ 6/3 = 9/x
→ 2 = 9/x
→ x = 9/2
x = 4.5 cm
ii) DE || BC
Hence ,
AD/DB = AE/EC [B.P.T]
→ (x+4)/(x+1) = (2x-1)/(x+1)
I hope you can try the second one yourself ehehehe +_+
