Answer 1

see explanation

Explanation:

If a line is parallel to a side of a triangle and it intersects the other 2 sides, it divides those sides proportionally,

(1)

`(1)/(4)` =
`(1)/(x)` ( cross multiply )

x = 4

(3)

`(8)/(x)` =
`(14)/(49-14)`, that is

`(8)/(x)` =
`(14)/(35)` ( cross- multiply )

14x = 280 ( divide both sides by 14 )

x = 20
