The mean of the ages of the men that are given will be 22.1.
<h3>How to calculate the mean?</h3>
It should be noted that mean simply means average. The mean of the men will be:
= (27 + 20 + 20 + 19 + 19 + 25 + 24 + 21 + 22 + 24) / 10
= 221/10
= 22.1
Therefore, the mean of the ages of the men that are given will be 22.1.

Answer :- Yes the two triangles are similar because there are two pairs of congruent corresponding angles.
Explanation:-
In Δ ABC
∠A=30° , ∠C=65 °
By angle sum property of triangle
∠A + ∠B + ∠C= 180°
⇒∠B= 180°-∠A-∠C=180°-30°-65°=85°
⇒∠B=85°
Now in ΔABC and ΔDEF
∠A=∠D=30° and ∠B=∠E=85°
⇒ there are two pairs of congruent corresponding angles.
So by AA-similarity criteria
ΔABC ≈ ΔDEF
