In any triangle, the sum of the angles is always 180 degrees. Given that both triangles have a right angle (90 degrees) and another angle of 53 degrees, we can find the measure of the third angle by using the formula:

\[
\text{Third angle} = 180^\circ - (\text{Angle 1} + \text{Angle 2})
\]

For Triangle JKL:
- Angle K = 90 degrees
- Angle L = 53 degrees

Calculating the third angle (angle J):

\[
\text{Angle J} = 180^\circ - (90^\circ + 53^\circ) = 180^\circ - 143^\circ = 37^\circ
\]

For Triangle YXZ:
- Angle Y = 53 degrees
- Angle X = 90 degrees

Calculating the third angle (angle Z):

\[
\text{Angle Z} = 180^\circ - (90^\circ + 53^\circ) = 180^\circ - 143^\circ = 37^\circ
\]

In both triangles, the measure of the third angle is \( \mathbf{37^\circ} \).
