Answer 1

Answer:

2

Step-by-step explanation:

AB/DB=AE/EC

1.5/6=X/8

X= 8/4=2

Answer 2

Question:

In the given figure ∆ABC ,DE || BC,AD =1.5 cm, DB=6 cm,AE = x cm EC =8 cm,then x = .….

a)2.5 cm

b)2 cm

c)3 cm

d)3.5 cm

Answer:

B) 2.

Given :

We have ∆ABC,

which sides are AD = 1.5 cm , DB 6 cm , AE = x cm and EC= 8 cm

And, DE || BC.

To Find the Value,

Side AE = x cm.

Solution :

DE || BC, so it's sides are equal,

Let side AE be x cm,

$\leadsto \tt \frac{AD}{DB} = \frac{AE}{EC} \\ \leadsto \tt \frac{1.5}{6} = \frac{x}{8}$

$\leadsto \tt \frac{1 \cancel{.}5}{60} = \frac{x}{8} \\ \leadsto \tt \frac{ \cancel{1 5}}{ \cancel{60}} = \frac{x}{8}$

$\leadsto \tt \frac{1 }{ \cancel4} = \frac{x}{ \cancel8} \\ \leadsto \tt x = 2 \: cm.$

Therefore, the value of x is 2 cm.
