find the value of C that completes the square then rewrite the resulting ti nominal as the square of a binomial x^2+8x+x

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

answer: 104.283185

step-by-step explanation:

3.14159265359 + 3.14159265359= 6.28318530718

since you're subtracting 3 twice, i'm just gonna say -6

6.28318530718 - 6 = 0.28318530718

0.28318530718 + 5 = 5.28318530718

5.28318530718 + 99 = 104.283185307
