Dear Piyush,
the angle opposite 22 is 60 degrees. Let third side be x,
from cosine law, 222=x2+242 -2*24*x*cos(60)
x2-24x+92=0
x=12±√52=12±2√13

```										let ABC be the triangle...
angles are in ap so 2B=A+C...........1
A+C=90-B..........2
from 1 and 2
B=60 and so A and C can be 30 and 90
now draw a triangle ABC right angled at C
AB is the hypotenuse therefore AB=24
let the other sides be 22 and x
now 24^2 =22^2 +x^2
X=+-2sqrt23
