It's important to know that the acute angles shown are not equal because their opposite sides are different 13 and 14, respectively.
Following this relation, we can deduct that the angle x+2 should be less than 37 because 13<14.

Subtract 2 from both sides.

This means that the values of x must be less than 35.
On the other hand, the angle x+2 must be greater than zero, otherwise, it wouldn't make any sense.

Subtract 2 from both sides.

This means the values of x must be greater than -2.
Then, we unite both intervales to make one.
[tex]-2
This interval means that the values of x must be between -2 and 35.
