well it would make sense to say that the longest fish is 12in longer than the shorter fish because if you take 21in (the longest fish) and subtract 9 (the shortest fish) you would get 12.
Hope that helped pls give brainlist
y=2x so replacr the -y with -2x so 2x+6 is 8x. :)
The answer should be acute and scalene. Sorry if I’m wrong though
The measure of one of its angles is 150°. The correct option is D.
<h3>How to calculate the angle?</h3>
The value of angles in a polygon is calculated by using the formula:
= (n - 2) × 180°
where n *+ number of sides
This will be illustrated as:
= (n - 2) × 180°
= (12 - 2) × 180°
= 10 × 180°
= 1800°
Since it has 12 sides, the value of each angle will be:
= Total angle / Total sides
= 1800° / 12
= 150°
The angle is 150°.
