If w, v, and u are the midpoints of triangle srt, find sr.

a.
1.7
b.
2.3
c.
3.4
d.
4.6

4.6

Step-by-step explanation:

W is the mid point of ST

U is the mid point of SR

V is the mid point of TR

Mid point theorem : It states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

So By theorem,

WU = 1.7

So,  

Since V is the midpoint of RT

So,

Basic Proportionality Theorem : It states that, if a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.

So, Using theorem :

So,

Thus the length of SR is 4.6

Hence Option D is true.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
