Answer 1

x = 4

Explanation:

the segment inside the triangle is an angle bisector and divide the opposite side into segments that are proportional to the other two sides, that is

`(x)/(x+4)` =
`(x+6)/(2x+12)` =
`(x+6)/(2(x+6))` =
`(1)/(2)` ( cross- multiply )

2x = x + 4 ( subtract x from both sides )

x = 4
