The measure of an interior angle of a regular nonagon (9-sided polygon) is 140°
<h3>How to determine the angle</h3>
The formula for sum of interior angles of a polygon is given as;
= ( n -2) × 180
Recall that a nonagon has nine sides, so , n = 9
Substitute the value into the formula
= ( 9 -2) × 180
= 7× 180
= 1260°
Since the sum of the angles = 1260°
One of the angles = 1260/ 9 = 140°
Therefore, the measure of an interior angle of a regular nonagon (9-sided polygon) is 140°

Answer:
Trigonometric ratio is the special measurements of a right triangle. There are three basic trigonometric ratios which are sine , cosine , and tangent.
Step-by-step explanation:
What is sine? The sine of an angle x is the length of the opposite side.
What is cosine? The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
What is tangent? The tangent of an angle is the length of the opposite side
Tangent and sine are very closely related and easily mixed up. Be carful with your calculations for the most accurate answer.
