Find the value of x One side is 87 degrees and 58 degrees on the other

no idea what x is supposed to represent.

One side of what?
useless post.

To find the value of x in your question, we likely have a triangle with two known angles: 87 degrees and 58 degrees.

However, the value of x cannot be determined based solely on this information because in a triangle, the sum of all three interior angles is always 180 degrees.

To find the value of x, we need one more piece of information, such as the measure of the third angle or the length of one of the sides.

If you have any additional information, please provide it, and I would be happy to assist you further.
