D = 2C
J = 1/3D
J = C - 1
J = 1/3D
J = 1/3(2C)
J = 2/3C
2/3C = C - 1
2/3C - 3/3C = -1
-1/3C = -1
C = -1 * -3
C = 3...there are 3 cats
J = C - 1
J = 3 - 1
J = 2.....there are 2 collars
Let 
be the legs of the triangle, with ![x[tex]\mathrm{area}_{\rm square} = y^2](https://tex.z-dn.net/?f=x%5Btex%5D%5Cmathrm%7Barea%7D_%7B%5Crm%20square%7D%20%3D%20y%5E2)
The square has 3 times the area of the triangle, so
Meanwhile, in the triangle we have
Now,
On the cube, it measures in numerical order 1 to 6, so:
1,2,3,4,5,6.
We are finding how much red fabric was used for even numbered sides.
So we are looking for sides 2,4,6
Since 20 in. is measured on a side, we can determine the area: 20*2= 40 in.^2 (all sides are same and length*width)
Now we have how much fabric is used on each side, so apply the area to all the even numbers (2,4,6)
40*3= 120 inches
Answer:
72°
Step-by-step explanation:
the top angle in the triangle=36° because alternate angles are equal
the triangle is an isosceles triangle hence the base angles are equal
the sum of angles in a triangle is 180°
180°=(36+i°+i°)
180=36+2i°
2i°=180-36
2i°=144
i°=144/2
i°=72°
