Answer 1

Answer:

18 units

Step-by-step explanation:

First, prove the two triangles formed are congruent to each other.

 Then, we will get that the 12 unit long line is perpendicular to the base.

So, by using Pythagoras theorem we get,

$\frac{x}{2} = \sqrt{15^{2}-12^{2} } = \sqrt{81}$

⇒$\frac{x}{2}=9$ ⇒ x= 18 units.

Hope this is clear.
