Find the value of x.

x = 66°

Step-by-step explanation:

In order to solve this, we need the sum of all interior angles which can be found by using the following formula where "n" is the number of sides the polygon has...

Now we use the formula and get...

180(n - 2) = 180(4 - 2) = 180(2) = 360

Now in order to find angle "x," we just substract the values of the other angles from 360, and so we get...

360° - 103° - 133° - 58° = 66°  

Now we know that x = 66°
