It seems like there's some confusion in your question due to the repeated use of "2." and the lack of operations or relations between the values. However, if you are trying to find an angle \( x \) given that it has some relation to 58° and 84°, you'll need to clarify what kind of relationship you're looking for.
For example, if you are looking for a value of \( x \) that is the average of 58° and 84°, you would calculate it like this:
\[ x = \frac{(58 + 84)}{2} = \frac{142}{2} = 71° \]
If you're looking for something else (like a complementary angle, supplementary angle, or solving a certain equation), please provide more detail.
