Find the angle marked x in each of these polygons. x=square ^circ [4] x=square ^circ [4]

## Step 1: Understand the formula for the sum of interior angles of a polygon.### The formula is: \( \mathbf{(n - 2) \times 180^\circ} \), where is the number of sides in the polygon.## Step 2: For each polygon, count the number of sides (or use the given number of sides) to calculate the total sum of the interior angles using the formula from Step 1.## Step 3: Add up the known angles provided in the problem.## Step 4: Subtract the sum of the known angles from the total sum of the interior angles to find the value of the missing angle .## Step 5: Apply the steps above to each polygon separately to find each missing angle.Given the lack of specific details for the polygons in the question, I will illustrate with a hypothetical example for a quadrilateral (4 sides) and a pentagon (5 sides).### Example for a quadrilateral:- Suppose the known angles are 90°, 80°, and 100°.- Total sum of interior angles = \( (4 - 2) \times 180^\circ = 360^\circ \).- Sum of known angles = .- Missing angle .### Example for a pentagon:- Suppose the known angles are 108°, 102°, 120°, and 90°.- Total sum of interior angles = \( (5 - 2) \times 180^\circ = 540^\circ \).- Sum of known angles = .- Missing angle .
