At its highest point, the elevation of a county is 5,776 feet above sea level. At its lowest point, the elevation of the county is 7 feet below sea level. What is the expression?

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

your answer is  

a.

5

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
