Answer 1

Answer:

$x=5$

Step-by-step explanation:

CE = EB since E is the midpoint of CB (proven by AD intersecting it).

If CE=EB, then:

$2x=15-x$

Add $x$ to both sides

$3x=15$

Divide both sides by 3

$x=5$

Answer 2

Answer:

5

Step-by-step explanation:

Since the diagonals of a parallelogram bisect each other, the two halves must be equal. Therefore:

$15-x=2x \\\\15=3x \\\\x=5$

Hope this helps!
