Consider u = {x|x is a negative real number}.
which is an empty set?
o
0
{xx e u and x has a negative cube root)
{x|x e u and x has a negative square root}
{x|x € u and x is equal to the product of a positive number and -1}
{xx € u and x is equal to the sum of one negative and one positive number}

c) yes, because of asa or aas

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
