She save from about $17.9 to $23.5
(not sure I did it right. Hope I helped :))
Step-by-step explanation:
Use triangle congruency:
BC=EC, AC=DC - Given
m∠DCE = m∠ACB because they are vertical angles
Therefore ΔABC ≅ ΔDEC because of Side-Angle-Side congruency
AB=DE because corresponding parts of congruent triangles are also congruent (CPCTC)
Answer:
3 + 
is irrational, as is an irrational number in itself, not being able to change into a fraction as it is a non-terminated number.
