Answer:
16.5mm to. 1 decimal place
Step-by-step explanation:
Please check attachment for diagrammatic representation of the triangle.
Since one of the angles of the triangle is 90, this means that we are dealing with a right angled triangle
To find the length of AC, we make use of pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the other two sides. The hypotenuse is the longest side of the triangle which we have as 17.88 mm
Mathematically therefore
17.8^2 = 6.6^2 + AC^2
AC^2 = 17.8^2 - 6.6^2
AC^2 = 283.28
AC = √(273.28)
AC = 16.53 mm
This is 16.5 to 1 decimal place
The 4 treads require 4*10.25 = 41 inches, but you also require landings at each level, adding perhaps 72 inches. (Building codes vary.)
Somewhere between 41 and 113 inches of horizontal space will be required, perhaps more.
Answer:
x = 5 units.
Step-by-step explanation:
In a parallelogram. diagonals bisect each other.
This means
.
![$ \implies 15 - x = 2x $](https://tex.z-dn.net/?f=%24%20%5Cimplies%2015%20-%20x%20%3D%202x%20%24)
![$ \implies 15 = 3x$](https://tex.z-dn.net/?f=%24%20%5Cimplies%2015%20%3D%203x%24)
.
Therefore, the length of x = 5 units.
Answer:
I'm not 100% sure but I believe the answer is 27
because -48/-4=12
12+15=27
