Answer:
The correct answer is: Δ ARS ≅ Δ AQT
Step-by-step explanation:
Given:
1) AR = AQ
2) ∠1 ≅ ∠3
If AR = AQ then ΔARQ is equilateral triangle, angles on the base of the equilateral triangle are the same.
3) ∠R ≅∠Q
According to this we have statement Angle-Side-Angle
Δ ARS ≅ Δ AQT

Answer:
167.27 mg.
Step-by-step explanation:
We have been given that the half-life of Radium-226 is 1590 years and a sample contains 400 mg.
We will use half life formula to solve our given problem.
, where N(t)= Final amount after t years,
= Original amount, t/2= half life in years.
Now let us substitute our given values in half-life formula.


Therefore, the remaining amount of Radium-226 after 2000 years will be 167.27 mg.
