To solve for $x$ in the triangle, we can use the fact that the sum of the angles in a triangle is always $180^\circ$.

The given angles are:

• $58^\circ$
• $35^\circ$
• $x$

Using the triangle angle sum property: $x + 58 + 35 = 180$

Simplify the equation: $x + 93 = 180$

Subtract 93 from both sides: $x = 180 - 93$ $x = 87$

So, the value of $x$ is $87^\circ$.

Answer: $x = 87^\circ$
