In triangle PQR, since it is a right triangle, the sum of the angles is 180 degrees. Given that Angle P is 90 degrees and Angle Q is 53 degrees, we can find the measurement of Angle R.

According to the triangle angle sum property:

\[
\text{Angle P} + \text{Angle Q} + \text{Angle R} = 180^\circ
\]

Substituting the known values:

\[
90^\circ + 53^\circ + x = 180^\circ
\]

Now, combine the angles:

\[
143^\circ + x = 180^\circ
\]

To isolate \(x\), subtract 143 degrees from both sides:

\[
x = 180^\circ - 143^\circ
\]

Calculating that gives:

\[
x = 37^\circ
\]

Therefore, the measurement of angle R is **37 degrees**.
