To find the measure of the exterior angle \( x \), we can use the property that an exterior angle of a triangle is equal to the sum of the two opposite interior angles.

In this triangle:

- One interior angle is \( 37^\circ \).
- The other interior angle is \( 42^\circ \).

Now, we calculate the sum of these two angles:

\[
37^\circ + 42^\circ = 79^\circ
\]

Therefore, the measure of the exterior angle \( x \) is \( 79^\circ \).

The answer is:

**79°**
