Answer 1

`\Large \boxed{\mathrm{B) \ 45}}`

Explanation:

We can solve the problem using ratios.

`\displaystyle (x)/(20) =(x+18)/(20+8)`

Cross multiply.

`20(x+18)=x(20+8)`

Expand brackets.

`20x+360=28x`

Subtract 20x from both sides.

`360=8x`

Divide both sides by 8.

`45=x`

Answer 2

the two lines are parallel, the angle they make should be equal and one angle is common so the triangles are similar by AAA.

Now the ratio of sides are
`(20+8)/(20)=(x+18)/(x)`

use divideno,
`\frac8{20}=\frac{18}x`

and then inverse the whole equation to get
`x=20*(18)/(8) \implies x= 45`
