Answer:
<h2>x = 27</h2>Step-by-step explanation:
BR is parallel to QC therefore ΔBDR and ΔQDC are similar.
The sides are in proportion:
We have
BD = 26 + 39 = 65
QD = 39
RD = 18 + x
CD = x
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 39x from both sides</em>
<em>divide both sides by 26</em>
