Answer:
P=88. L=3w
P= 2(w)+2(L)
Then substitute the values into the equation
88=2w+2(3w)
Then solve for w and its length which is 3w
If you triple the ginger, to be able to keep proportion, you would need triple the nutmeg as well.
Use the sin identity to find that side. Sin(30) = a/12...12 sin(30) = a, and a = 6
We know that
The exterior angle measures of a polygon must add up to 360°,
therefore
360°/72°=5 exterior angles
so
5 exterior angles, would mean 5 interior angles and therefore 5 sides to the polygon
The exterior angle and the interior angle of any polygon are supplementary and must add up to 180°.
exterior angle+interior angle=180°
interior angle=180°-exterior angle
interior angle=180°−72°-------> 108°
Each interior angle is 108°
The sum of the interior angles would be
5*108°=540°
the answer is
540°
