• Sum of Angles: 180(n - 2)°

Explanation:

Step 1: Identify

We have a polygon, so n = 4.

1. Substitute [SA]: 180(4 - 2)°
2. (Parenthesis) Subtract: 180(2)°
3. Multiply: 360°

This tells us the sum of all angles in the shape.

Step 2: Solve for x

1. Set up equation: 90° + 93° + 89° + x° = 360°
2. Combine like terms: x° + 272° = 360°
3. Isolate x: x = 88°
