Answer
yes
Work Step by Step
The hypotenuse is longer than the legs, so if the given measurements are the lengths of the sides of a right triangle then:
$12^2+35^2\overset?=37^2\longrightarrow$ use a calculator
$144+1225\overset?=1369\longrightarrow$ add
$1369=1369\checkmark$
Since the given measurements satisfy the equation $a^2+b^2=c^2$, the lengths could represent the sides of a right triangle.
