what is the exterior angle is 42+37=x

The sum of the exterior angles of any polygon is always 360 degrees.

Therefore, we can rewrite the equation as:

42 + 37 + x = 360

Simplifying further:

79 + x = 360

To isolate x, we subtract 79 from both sides:

x = 360 - 79

Therefore, the value of x is 281.
