Question

Find the value of X to the nearest tenth.
39.0
60.0
15.5
31.0

Answer 1

`(2x)/(39)=(62)/(39+39)\\\\(2x)/(39)=(62)/(78)\ \ \ \ |cross\ multiply\\\\2x\cdot78=39\cdot62\\\\156x=2418\ \ \ \ |divide\ both\ sides\ by\ 156\\\\\boxed{x=15.5}`

Answer 2

`x=15.5`

Explanation:

We are given with the diagram with mid segment in a triangle

If we have a mid segment in a triangle and it is parallel to the other side then we use formula

mid segment = half of base of the triangle

`2x= (1)/(2) * 62`

`2x= (62)/(2)`

`2x=31`

Divide both sides by 2

`x=15.5`

The value of
`x=15.5`
