Question

AJUTOR!Multumesc anticipat​

Answer 1

Răspuns:

$\overrightarrow{BQ}=\displaystyle\frac{1}{2}\left(\overrightarrow{BA}+\overrightarrow{BC}\right), \ \overrightarrow{CP}=\displaystyle\frac{1}{2}\left(\overrightarrow{CA}+\overrightarrow{CB}\right)$

Atunci

$\overrightarrow{BQ}+\overrightarrow{CP}=\frac{1}{2}(\overrightarrow{BA}+\overrightarrow{BC}+\overrightarrow{CA}+\overrightarrow{CB)}=\frac{1}{2}(\overrightarrow{BA}+\overrightarrow{CA})$
