I'm helping someone with her daughter's homework. What is the term for this definition: take a part a number to write it in a ne

This looks fun
ok so
we will use subsitution
xy=-10
divide both sides by x or y (I will choose y)
x=-10/y
sub -10/y fo x
(-10/y)^2+y^2=36
100/(y^2)+y^2=36
times both sides by y^2
100+y^4=36y^2
minus 36y^2 from both sides
y^4-36y^2+100=0
(y^2)^2-36(y^2)+100=0
quadratic formula
for
ax^2+bx+c=0
x=
x=
x=
sub
y=-10/x
y=
so x+y=+
multiply first number by
and add them
x+y=
or
x+y=

When you illustrate the problem, an image like that shown in the picture is formed. You are asked to order the angles in increasing order. Since, it did not ask for the values, we don't have to solve it.
Note that the larger the angle, the larger its opening, thus its opposite side would be larger also. Using this analogy and referring to the picture, the order of angles should be: Angle E < Angle F < Angle D
