Answer:
It is an irrational number
Step-by-step explanation:
An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.
Answer:
Step-by-step explanation:
You add up all the sides of the shape to find the perimeter
Answer:
161.5 in.^2
Step-by-step explanation:
Since you don't have a figure, from your description, I understand that the base of each small upper triangle is 8.5 inches. That means that each small triangle on top has a base of 8.5 inches and a height of 5 inches, and each small triangle below has a base of 8.5 inches and a height of 13 inches. My calculations below are base don this understanding.
The area of a kite is
A = (Bb)/2
where B and b are the lengths of the diagonals.
The diagonals have lengths:
B = 13 in. + 6 in. = 19 in.
b = 8.5 in. + 8.5 in. = 17 in.
A = (Bb)/2
A = (19 in. * 17 in.)/2
A = (323 in.^2)/2
A = 161.5 in.^2
That's a right triangle
remember, if the legs of a right triangle measure a and b and the hypootnuse is c then a²+b²=c²
so
hypotnuse is longest side, the one oposite the right angle
in this case, it is 5
one leg is 4
and the other one is red, let's call it x
so
x²+4²=5²
x²+16=25
minus 16 both sides
x²=9
sqrt both sides
x=3
the length of the red vertical edge is 3cm
