Question

In the given figure DEllBC find x


please give me anwer brother and girlsfriend​

Answer 1

Answer:

Step-by-step explanation:

Step-by-step explanation:Given: ABC is a triangle, DE || BC, AD = x, DB = x - 2, AE = x + 2 and EC = x - 1.

To find: x

In △ABC, we have  

DE || BC

Therefore [By Thale's theorem]

AD/DB = AE/EC

AD × EC × = AE × DB

x(x-1) = (x-2)(x+2)

x2 - x = x2 - 4

x = 4

hope it helps

Answer 2

$\frac{x}{7.2} = \frac{1.8}{5.4}$

$5.4x = 1.8 \times 7.2$

$x = 2.4$
