Question

Which value of x would make TV || OS? 3 8 10 11

Answer 1

Answer:

For x = 10, the lines will be parallel

Step-by-step explanation:

For parallel lines in a triangle, their sides must be proportional

And,

$\frac{x+4}{x-3} = \frac{x+10}{x}$

Cross Multiplying

=> x(x+4) = (x-3)(x+10)

=> $x^2+4x = x^2+7x-30$

=> $x^2-x^2+7x-4x = 30$

=> 3x = 30

Dividing both sides by 3

=> x = 10
