Question

A regular polygon has 12 sides. Work out the size of each interior angle.​

Answer 1

Answer:

150°

Step-by-step explanation:

Measure of each interior angle of polygon

$= \frac{(n - 2) \times 180 \degree}{n} \\ \\ = \frac{(12 - 2) \times 180 \degree}{12} \\ \\ = \frac{10 \times 180 \degree}{12} \\ \\ = 10 \times 15 \degree \\ \\ = 150 \degree$
