Answer:
−15+5h
Step-by-step explanation:
Given:
M is the mid-point of RS
N is the mid-point of ST
MN = 18.4
To find:
The length of RT.
Solution:
The reference image is attached below.
Joining mid-point M and N, we get mid-segment MN.
MN is parallel to RT.
Triangle mid-segment theorem:
If a segments joins the mid point of a two sides of triangle, then the segment is parallel to the third side and is half of that side.
![$\Rightarrow MN=\frac{1}{2} RT](https://tex.z-dn.net/?f=%24%5CRightarrow%20MN%3D%5Cfrac%7B1%7D%7B2%7D%20RT)
Substitute MN = 18.4
![$\Rightarrow 18.4 =\frac{1}{2} RT](https://tex.z-dn.net/?f=%24%5CRightarrow%2018.4%20%3D%5Cfrac%7B1%7D%7B2%7D%20RT)
Multiply by 2 on both sides.
![$\Rightarrow 2\times 18.4 =2\times \frac{1}{2} RT](https://tex.z-dn.net/?f=%24%5CRightarrow%202%5Ctimes%2018.4%20%3D2%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%20RT)
![$\Rightarrow 36.8=RT](https://tex.z-dn.net/?f=%24%5CRightarrow%2036.8%3DRT)
The length of RT is 36.8.
8÷1/3=24 so the answer is C
