Marvin and Alicia are putting new carpet in their living room. The carpet costs $4.15 per square foot and $97 to have it installed. Their total bill before sales tax is $1798.50.

Part A:
Write an equation that represents how many square feet (s) their living room is.

Part B:
How many square feet is their living room?

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

hi im bob : l

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
