128 feet

56 feet

100 feet

72 feet

Answer 1

@mhmdrz91 can you help me with this one too please

Answer 2

\[AB \left| \right|RQ \rightarrow \frac{ PA }{ PR } = \frac{ PB }{ PQ } = \frac{ AB }{ RQ }\]and\[BC \left| \right|PR \rightarrow \frac{ QC }{ QR } = \frac{ QB }{ QP } = \frac{ BC }{ PR }\]

Answer 3

try to use above formulations for finding AB and BC... try ;)
