Answer:
A. Triangles are similar by AA similarity.
Step-by-step explanation:
By the Angle Angle Similarity Theorem, if two pairs of corresponding angles are congruent, then the triangles are similar. As a given, Angle E is 35 degrees and Angle B is 45 degrees, which means that Angle R is 100 degrees; By definition, a triangle is 180 degrees in total. Therefore, Angle R is congruent to Angle A. Angles REB and AEZ are also congruent by the vertical angle theorem.
In conclusion, triangles AEZ and REB are similar by the AA similarity theorem.
Answer: Medication in Lexi's system on day t becomes,

Step-by-step explanation:
Since we have given that
Initial amount Sofia takes of a medicine = 10 mg
Concentration in blood decreases by a factor of one half every day.
So, it becomes,

According to question, four days later, it becomes,

We have given that Lexi takes 10 mg of the same medicine.
So, it becomes,

Hence, Medication in Lexi's system on day t becomes,

B+3> 7 and. b+3< -7
-3 -3 -3. -3
b>4 and b<-10
