ABCD is a parallelogram. Determine the length of AD.
ale4655 [162]

Answer:

  D)  10 units

Step-by-step explanation:

Opposite sides of a parallelogram are congruent.

__

<h3>setup</h3>

The relation between opposite sides tells you ...

  BC = AD

  2x = x +5

<h3>solution</h3>

  x = 5 . . . . . . . subtract x from both sides of the equation

We want the length of AD, which is ...

  AD = x +5 = 5 +5

  AD = 10

_____

<em>Additional comment</em>

Often, it seems like the question is answered once the value of x is found. Here, finding the value of x is an <em>intermediate step</em>. The value of x is needed in order to be able to answer the question about <em>the value of an expression involving x</em>.
