Answer:
If KE = OS then we can deduce that the trapezoid is constructed of 3 equilateral triangles and thus we can easily work out the angles.
OSK = 60
SKE = 120
KEP = 120
EPO = 60
We can also easily work out the perimeter since we can deduce that PE = SK = KE and thus the perimeter is 5 * 8 = 40
In the addition/subtraction method, the two equations in the system are
added or subtracted to create a new equation with only one variable. In
order for the new equation to have only one variable, the other variable
must cancel out. In other words, we must first perform operations on
each equation until one term has an equal and opposite coefficient as
the corresponding term in the other equation.
