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.

NEED HELP WITH

Fed [463]

Let the average profit or loss in year 2006 be x millions,

The average profit for the 8-year period, is the total sum of the profits (or losses) of each year, divided by 8:

so we have:

$\displaystyle{ \frac{3.40+2.10+x+0.60+2.10+0.20+1.30+0.75}{8}=1$

$\displaystyle{\frac{10.45+x}{8}=1$

$10.45+x=8$

x=8-10.45=-2.45

Answer: the loss in 2006, was 2.45 million dollars
