Question

दिए गए चित्र में DE||BC तो x का मान ज्ञात करें​

Answer 1

Step-by-step explanation:

$x = x + 3 \\ 3x + 4 = 3x + 19 = x = 2$

Answer 2

Given :  DE||BC

To find : Value of x

Step-by-step explanation:

DE || BC

Hence using Basic proportionality theorem ( Thales theorem)

AD/BD = AE/CE

AD = x

BD =  x-2

AE=x+2

CE = x - 1

=> x/(x - 2)  = (x + 2)/(x-1)

=> x² - x  = x² - 4

=> x = 4

AD = 4

BD = 2

AE = 6

CE = 3

4/2 = 6/3 = 2

Value of x = 2
