The answer should be (3,1)
Create formulas for length and perimeter.
L = 4/W
10 = 2*L + 2*W
Substitute formula for length for the length in perimeter formula
10 = 2*4/W + 2*W
10 = 8/W + 2*W
5 = 4/W + W
5W = 4 + W^2
0 = 4 - 5W + W^2
W^2 -5W + 4 = 0
You now have a standard quadratic equation with A=1, B=-5, and C=4
Using the quadratic formula you get two possible answers
W = 1, or W = 4
Let's check them
Width = 1, L = 4/1 = 4
Width = 4, L = 4/4 = 1
Both make the same 1x4 rectangle. And the perimeter is 2*1 + 2*4 = 2+8 = 10
Answer:
26°
Step-by-step explanation:
same side same angle
the total of angles in triangle is always 180
No other regular polygon can tessellate because of the angles of the corners of the polygons. In order to tessellate a plane, an integer number of faces have to be able to meet at a point. For regular polygons, that means that the angle of the corners of the polygon has to divide 360 degrees.
