For the first picture

|AB| |BD|
=
|AC| |DC|

x+8 10
=
2x-5 14

10(2x-5)=14(x+8)

20x-50 = 14x+112

20x-14x = 112+50

6x = 162

x= 162/6

x=27

For the second picture

AD| |AC|
=
|DB| |CB|

3 4
--=---
x 7.5

4×X = 3×7.5

x = 22.5/4

x = 5.625

< i think this is the answer unless i did my math wrong
