Question

In triangle ABC Ab=6cm and DE//BC such that AE=1/4AC find length of AD

Answer 1

Answer:

use basic proportionality theorem

AD/AB = AE/AC

AD/6 = 1/4

AD = 6/4

AD = 3/2 cm

Answer 2

Answer:

AD=1.5cm

Step-by-step explanation:

we know that AE=1/4AC

cross multiplying we get:-

AE/AC=1/4.

but we know that DE//BC

therefore by BPT. We get AD/AB=AC/AE

then we can say that AD/AB=1/4

AD/6=1/4  (because AB=6cm so we substitute the value of AB in the equation)

then AD=6/4

AD=3/2

AD=1.5cm
