Answer:
Step-by-step explanation:
In Δ PQS and ΔPQT
∠QPS = ∠RPT       {Common angle}
∠PSQ = ∠PTR = 90°         {QS & RT are altitude}
QS = RT                            {given}
ΔPQS ≅ ΔPRT               {A A S congruent}
PQ = PS                         {CPCT}
So, PQR is an isosceles triangle.

Answer:
His age is 7 years.
Step-by-step explanation:
Let Rehman's  present age be x years.
1 / (x - 3) + 1 /(x + 5) = 1/3
Multiply through by the LCD 3(x - 3)(x + 5):
3(x + 5) + 3(x - 3) = (x + 5)(x - 3)
3x + 15 + 3x - 9 = x^2 + 2x - 15
x^2 + 2x - 6x - 30 + 9 = 0
x^2 - 4x - 21 = 0
(x - 7)(x + 3) = 0
x = 7  (answer).
