a estrutura metálica representada na figura a seguir mostra o processo de construção de um galpão industrial. Tres vigas são representadas pelas retas r, s,e t, em que r e s são comcorrentes e perpendiculares. Além disso, as retas s e t são paralelas. A partir das informações anteriores, pode_se afirmar qud as retas r e t são :

you can not solvr this without numbers

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
