Question

In the figure , if DE is parallel to BC, find AD

Answer 1

Answer:

As DE is parallel to BC

AD/DB=AE/EC(By BPT)

=>AD/7.2=1.8/5.4

=>AD=7.2/3

=>AD=2.4cm

Answer 2

Answer:

Step-by-step explanation:

Ad/db x as /ec

Ad/7.2 x 1.8/5.4

5.4/7.2x1.8=ad (cross multiple)

5.4/12.96=ad

2.4=ad

Therefore, AD=2.4
