The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3
t ≤ 3 + 37 - t + 37 ≤ 3
t ≤ 40 - t ≤ 3 - 37
- t ≤ - 34 / * ( - 1 )
t ≥ 34
Answer t ∈ [ 34°C, 40° C ].

Answer:
As radius is perpendicular to tangent,
By pythagoras theorem :
x² = (x + 9)² - 15²
x² = x² + 18x + 81 - 225
18x = 207
x = 11.5
