It seems quite impossible to solve this question though. I have a way to solve this using a triple simultaneous equation, but it is quite tedious. you mind sharing how you find the answer for line AD?
hello, sure thing ! will share my workings for line AD : 9/AD = AD/16
AD^2 = 16x9
AD = 12
AD^2 = 16x9
AD = 12
Your method is simpler than mine, but you miss out that the whole diagram can be separated into three triangles, you can repeat the same method on the third triangle to solve for AB
