Answer:
a number
Step-by-step explanation:
this was asked in april so i rly think you need an answer anymore
We have to find the lengths of the diagonals KM and JL:
d ( KM ) = √ (( - a - b )² + ( 0 - c )²) = √ (( a + b )² + c² )
d ( JL ) = √ ( ( a - ( - b ) )² + ( 0 - c )²) = √ ( ( a + b )² + c² )
So the lengths of the diagonals KM and JL are congruent.
The lengths of the diagonals of the isosceles trapezoid are congruent.
First subtract 8 from both sides
leaving you with x/2 = -20
Then multiply both sides by two to get rid of the denominator
which leaves you with x = -40
