Esmeralda has a magnet in the shape of a square. Each side of the magnet is 3 inches long, what is the perimeter of her magnet
1 answer:
ANSWER
The perimeter is 12 inches.
EXPLANATION
The formula for calculating the perimeter of a square is
Since the magnet is in the form of a square, we can use this formula to find the perimeter of the magnet.
It was given that, each side of the magnet is 3 inches long.
Hence, we have l=3 inches.
We have to substitute l=3 into the formula and simplify.
The perimeter is

Answer:
44°
Step-by-step explanation:
The reference angle is the magnitude of the smallest angle between the terminal ray and the x-axis.
Your angle is one full circle clockwise plus 44° more (-360° -44° = -404°), so makes an angle of -44° with respect to the positive x-axis. The magnitude of that is 44°.
_____
<em>Using a function</em>
The attachment shows a calculator function that can be used to find the reference angle for any angle. (Replace the value -404 with the angle of your choice.)
