Answer:
y = 38
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the angles in the large outer triangle, then
x + 46 + 78 = 180
x + 124 = 180 ( subtract 124 from both sides )
x = 56
Consider the 3 angles in the smaller inner triangle, then
y + x + 86 = 180 , that is
y + 56 + 86 = 180
y + 142 = 180 ( subtract 142 from both sides )
y = 38
The perimeter of the room will be 
feet
<h3>Area of a square</h3>
A square is quadrilateral with 4 sides. The formula for calculating the area of the shape is given as:
A = L²
Given the following parameters
A = 
Substitute
L²
Determine the perimeter
Perimeter = 4L
Perimeter = 4(14x^6y^5z^3)
Perimeter =
Hence the perimeter of the room will be feet

Answer:
B) 1 < x < 13
Step-by-step explanation:
use triangle inequality theorem which states that the sum of any two sides must be greater than the third side
let x = third side
6 + 7 > x; x < 13
6 + x > 7; x > 1
x + 7 > 6; x > -1
there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative
