Answer:
s = 25
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is
half the length of the third sise , that is
TW = [tex]\frac{1}{2} [/tex] UV , substitute values
s = [tex]\frac{1}{2} [/tex] (s + 25) ← multiply both sides by 2 to clear the fraction
2s = s + 25 ( subtract s from both sides )
s = 25
