Answer:
The value of x = 6
Explanation:
The Midsegment of a triangle theorem states that the midsegment of a triangle is parallel to the third side of the triangle and it’s always equal to the one half or 1/2 of the length of the third side.
Now we can conclude that from the given triangle, the length of midsegment is 5x-1 which is parallel to the side of length 58, and will always equal to 1/2 of the length of the side of length 58.
Mathematically it means:
![5x-1\:=\:(58)/(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/y6sjlv9wc6xavdy0nexokxuagej9ri9fo1.png)
solving to find the length of x
![5x-1=29](https://img.qammunity.org/2021/formulas/mathematics/high-school/76rxh6j47h4lss1wjcz4urv07jfgx5dr8h.png)
Add 1 to both sides
![5x-1+1=29+1](https://img.qammunity.org/2021/formulas/mathematics/high-school/xlrg0e3hl1ltpeu0wwafenpt3if0lx0kyv.png)
![5x=30](https://img.qammunity.org/2021/formulas/mathematics/middle-school/qlrjzposoctwda0kqyxl166rlrmpsiemjg.png)
Divide both sides by 5
![(5x)/(5)=(30)/(5)](https://img.qammunity.org/2021/formulas/mathematics/high-school/sgybnpi400adhqv0gdczlloed519g6dgs7.png)
![x=6](https://img.qammunity.org/2021/formulas/mathematics/high-school/nzo8scb8znl8ef5cz3hap4phamcv7nzmgh.png)
Therefore, the value of x = 6
