Answer:

The answer to your question is: 21

Step-by-step explanation:

Data

AB = BC = CD

BQ = 21

QD = ?

PC = 11

Process

Here there are 2 triangles

ΔQCB and ΔQCD

These triangles share one side QC

And one side measures the same BC = CD

And the ∠ BCQ = ∠ DCQ

Then these triangles are congruents  SAS

if QB = 21 then QD = 21
