Please don't just provide an answer without showing your work. I recommend not using brute force as a method too.

Leg a = a

Leg b = b

 

By perimeter:

a+b+37=84

a+b=47

 

By Pythagorean Theorem:

a2+b2=372

 

Substitution:
a2+(47a)2=372

 

Solving:

a^2+(47-a)^2=37^2 = {a=12, a=35}

 

a = 12

b = 35

 

or

 

a = 35

b = 12
