Question

in the figure a b c d e parallel to a b is equal to 7 cm CD is equals to 5 cm and BC is equals to 18 cm find BE​

Answer 1

Answer:

10.5cm

Step-by-step explanation:

Let BE =x

since DE||AB

by Basic Proportionality Theorem(BPT)

AD/AC=BE/BC

therefore,

7/12=x/18

7*18=12x

126=12x

x=126/12

x=10.5cm
