The level of confidence represents the expected proportion of intervals that will
contain the parameter if a large number of different samples of size n
is obtained. It is denoted by <span>(1 - ∝) * 100%</span>.
Isosceles triangle has 2 sides that are the same length. So what you have is three sides that measure: x, x, and (x-8). 70 = x + x + (x-8). 70 = x + x + x - 8 78 = 3x x = 26. and 26 - 8 = 18. So two of your sides are 26 inches and the last side is 18 inches.
