Step-by-step explanation:
hello :
the perimeter of triangle is : P= (x-z+yx)+( z+x+xz)+A
given P=x+y+xy calculate the third side A
x+y+xy = (x-z+yx)+( z+x+xz) so : A=x+y+xy -x+z-yx-z-x-xz....continu
a=
Answer:
y - x - yz
Step-by-step explanation:
to find the third side , subtract the sum of the 2 given sides from the perimeter, that is
x + y + xy - ( x - z + yx + z + x + xz)
x + y + xy - (2x + yx + xz)
x + y + xy - 2x - yx - xz
y - x - xz
