To find the measure of the interior angle of a polygon, we have the formula...

(n - 2) × 180°

where n is the number of sides. As far as I know, tridecagon have 13 sides.

(13 - 2) × 180°
11 × 180° = 1980

Therefore, the measure of the interior angle of a regular tridecagon is 1980°

Tridecagon = 13-sided polygon

Measure of an/each interior angle of a tridecagon:

 \frac{180(n-2)}{n}     where n = number of sides

 \frac{180(13-2)}{13}

 \frac{180(11)}{13}

 \frac{1,980}{13}

≈ 152.31 degrees.

ANSWER:  An interior angle of a regular tridecagon measures approximately 152.31 degrees.

To find the sum of the measures of the interior angles of tridecagon:
Sum of interior angles = 180° (13-2)
                                    = 180° (11)
                                    = 1,980°
