Answer 2

Step-by-step explanation:

Given that:

DE||BC

To find : Value of x

Solution: As DE||BC

if in a triangle a line is drawn parallel to any side of the triangle ,then Basic Proportionality theorem can be applied

According to BPT

$\frac{AD}{DB} = \frac{AE}{EC}$

put the given values

$\frac{x}{7.2} = \frac{1.8}{5.4} \\ \\ x = \frac{18}{54} \times 7.2 \\ \\ x = \frac{1}{3} \times 7.2 \\ \\ x = 2.4 \: cm$

Thus,value of x is 2.4 cm

Hope it helps you.
