Question

If 5x-1 and 5x-19 form a linear pair, find x.​

Answer 1

Answer:

5x-1°+5x-19°=180°. (Linear pair)

10x-20°= 180°

10x= 180°+20°

10x =200°

x=20°

Answer 2

Answer:

Required value of x is 20°.

Step-by-step explanation:

Given, 5x-1 and 5x-19 from a linear pair.

We know,sum of angles in a linear pair is always equal to 180°.

According to question,

$(5x - 1) + (5x - 19) = 180$

we are separating variable and constant part,

$5x + 5x = 180 + 1 + 19$

We are adding 5x and 5x,

$10x = 180 + 1 + 19$

$10x = 200$

$x = \frac{200}{10}$

So,

$x = 20$

Required value of x is 20°.
