Answer:
Well, it keeps going down in 15s, so I'm guessing it's a geometric sequence. I wouldn't know about common ratio though...
17 feet
Step-by-step explanation:
15^2 + 8^2 = c^2
15^2 + 8^2 = 289
square root of 289 is 17
Answer:
Step-by-step explanation:
For side length s the area of the triangle is
.. A = (√3)/4*s^2
The radius of the circle will be
.. r = s/(2√3)
so the area of the circle is
.. A = π*r^2 = π*s^2/12
The fraction of the triangle that is not in the circle is
.. 1 - (π/12)/((√3)/4)
.. = 1 -π/(3√3)
.. ≈ 39.54%
Because these are opposite and they both have complimentary angles, you can set them equal to each other and solve for x
