All of the centra angles in a regular polygon must add up to 360 degrees. Also, because you're told that it is a regular polygon, the "regular" indicates that all of the central angles will be the same. Divide 360 degrees by 18 degrees to get the number of central angles, which is the same as the number of sides. 360/18 = 20. Therefore, the polygon has 20 sides. Hope that helps!
Y^2 -11y = 0
We can factor it:
y * (y -11) = 0
So y = 11, 0

Answer:
Step-by-step explanation:
Recall the mnemonics SOH CAH TOA.
SOH means the Sine ratio is Opposite over Hypotenuse.
This implies that;
The side opposite to angle A is 4cm and the hypotenuse is 5cm.
Well the easiest way to figure out this question is to just divide it by 4, like quarters, so 1000 divided by 4 is 250. so the other bakery was only 250. hope this helped
