An octagon has eight sides
Answer:
It = 1
Step-by-step explanation:
25-24.75=0.25
0.25 / 25= 0.01
0.01 * 100 = 1
Answer:
A = a^2.....the Area (A) of a square = a^2...where a = one side
79 = a^2...now take the sqrt of both sides, this eliminates the ^2
sqrt 79 = a
8.888 rounded = 8.89 = a......so one side = 8.89 ft
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
Let PS = x and RP = x-5
Using Pythagorean theorem on the two smaller rt triangles formed,
6^2 + x^2 = (ST)^2
6^2 + (x-5)^2 = (RT)^2
Now use Pythag on big triangle and sub in above values:
(2x-5)^2 = 6^2 + x^2 + 6^2 + (x-5)^2
Multiply out and simplify to
x^2 - 5x -36 = 0
Factor the quadratic: ((x-9)(x+4)=0 Therefore x=9 or x=-4. We may disregard the negative answer so x = 9. So PS is 9 and RP is 4.
Therefore entire hypotenuse is 4 + 9 or 13.
