Ta có: \(\widehat{M}+\widehat{N}+\widehat{P}+\widehat{Q}=360^0\)
\(\Leftrightarrow4\cdot\widehat{Q}=180^0\)
\(\Leftrightarrow\widehat{Q}=45^0\)
\(\Leftrightarrow\widehat{P}=135^0\)
Tứ giác MNPQ có:
\(\widehat{M}+\widehat{N}+\widehat{P}+\widehat{Q}=360^0\)
\(\Rightarrow120^0+60^0+3.\widehat{Q}+\widehat{Q}=360^0\)
\(\Rightarrow4.\widehat{Q}=180^0\)
\(\Rightarrow\widehat{Q}=45^0\)
=> Góc P = 1350
