Answer:

( n − 2 ) × 180

Step-by-step explanation:

The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

Answer:

$x=11$

Step-by-step explanation:

Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)

Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)

Since the angles in a triangle add up to 180 degrees ,

$33+(180-4x)+x=180$

Remove brackets:

$33+180-4x+x=180$

Add/Subtract:

$213-3x=180$

Subtract 213 from both sides:

$213-3x-213=180-213$

$-3x=-33$

Divide both sides by -3:

$\frac{-3x}{-3}=\frac{-33}{-3}$

$x=11$
