Answer:
-13=5+x, rearrange the terms.
-x=5+13, add.
-x=18, invert the sign.
x=-18
Since cube has all faces as Squares
perimeter of each face P = 22.2
as we know perimeter of a square is P = 4 * ( Sides of a square )
let the sides of the square be 'x'
Hence , 22.2 = 4 * x
=> x = 22.2/4
=> x = 5.55
hence the edge's length is 5.55
Note : if the length from edge to edge is asked then
Length of the Diagonal for a cube =

Hence we get edge to edge length as
√3 * 5.55 = 9.612

Step-by-step explanation:
Answer:
m∠1 is 49° and m∠3 is 49°
Step-by-step explanation:
In the given figure
∵ There are 2 parallel lines
∵ A transversal cuts them
∴ ∠4 and ∠8 are corresponding angles
→ Corresponding angles are equal in measures
∴ m∠4 = m∠8
∵ m∠8 = 131°
∴ m∠4 = 131°
∵ ∠1 and ∠4 formed a pair of linear angle
∵ The sum of the measures of the linear angles is 180°
∴ m∠1 + m∠4 = 180°
→ Substitute ∠4 by 131°
∴ m∠1 + 131° = 180°
→ Subtract 131 from both sides
∵ m∠1 + 131 - 131 = 180 - 131
∴ m∠1 = 49°
∵ ∠1 and ∠3 are vertically opposite angles
∴ m∠1 = m∠3
∵ m∠1 = 49°
∴ m∠3 = 49°
