The triangle is an equilateral triangle -- which also makes it equiangular.
Since there are 180° in a triangle, how many degrees are in each angle? _______
Also, since there are 180° on each side of a line, after you subtract the number of degrees in the angle of the triangle, how many degrees are left for the external angle? ________
If it's the question that I found, I could certainly be wrong; but I arrived at 2 for the answer, not 1. (Again -- my answer could be wrong ...)
n/20 = 4
Multiply both sides by 20:
20(n/20) = 20(4)
n = 80
Amount Spent = 3(2.45) + (1)(2.59) + (4)(0.79)
If the two points are (x1, y1) and (x1, y2), the slope of the straight line that passes through those two points is: m = (y2 - y1) / (x2 - x1)
If (x1, y1) = (-1, -1) and (x2, y2) = (2, 8), then
m = (8 - -1) / (2 - -1) = 9/3 = 3
The quick answer is that it is the square of the correlation coefficent.

192 = 64·3
(192)^(1/3) = (64)^(1/3)·(3)^(1/3) = 4·(3)^(1/3)
Archimedes, by measuring inscribed polygons (insided a circle) and circumscribed polygons (around a circle) pinned the value of pi between 3 1/7 and 3 10/71.
3 1/7 = 3/142857 ...
pi = 3.1415926535...
3 10/71 = 3/14084507 ...
Many, many centuries later, pi because identified with infinite series, so now pi is calculated with computers.
Can you rephrase the question? I got lost ...
Is your question, where is the square root button on this calculator?
There is a square root (√) button.
