Question

In the given figure , if DE parallel BC and AB=7cm then caculate x

Answer 1

where's the figure dear?

Answer 2

Answer:6 cm

Step-by-step explanation

IN TRIANGLE ADE&ABC

DE//BC

ANGLE ADE=ABC

ANGLE AEC=ACB

(CORESPONDING ANGLES)

SO, ∆ABC~ ∆ADE

THEREFORE

AD/AB=DE/BC

AD=3 AND AB= 7

SO,

3/7=x/14

3/7×14=x

X=6cm
