The geometry is that the number of sides for a 15- gon is 15 sides and the angles are 156° each.
<h3>How to calculate the angle?</h3>
The total angles in a 15 gon will be calculated as:
= (n - 2) × 180
= (15 - 2) × 180
= 2340
The value of each angle will be:
= 2340/15
= 156°
The total angles in a 16 gon will be calculated as:
= (n - 2) × 180
= (16 - 2) × 180
= 2520
The value of each angle will be:
= 2520/16
= 157.5°

Answer:
The Arabian Sea has two important branches — the Gulf of Aden in the southwest, connecting with the Red Sea
Step-by-step explanation:
number 2 the red sea
I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.
