Answer:
DE = 5 cm
Step-by-step explanation:
Using the midline theorem.
A segment joining the midpoints of 2 sides of a triangle DE and parallel to the third side BC is one half the length of the third side, that is
DE = 0.5BC = 0.5 × 10 = 5
In this quadratic equation a=9 b=0 c=64, you could use the Quadratic Formula:
x = [-b +-sqrt (b^2 -4*a*c)] / 2*a
x = 0 +- sqrt (0 -4*9*64) / 2*9
x = +- sqrt(-2,304) / 18
x = + 48 i / 18
x = -48 i /18
Where "i" is the square root of minus 1.
