Question

Tìm x?

Answer 1

Xét tứ giác MNQP có :

^M + ^N + ^Q + ^P = 360^o

=> 3x + 4x + 2x + x = 360^o

=> 10x = 360^o

=> x = 36^o

Vậy x = 36^o

Answer 2

vì M+N+Q+P=360^o

=>3x+4x+2x+x=360^o

=>10x=360^o

=>x=360:10

x =36 ^o

=> P= 36^o

Answer 3

Xét tứ giác MNPQ, ta có:

\(\widehat{M}+\widehat{N}+\widehat{P}+\widehat{Q}=360^o=>3x+4x+2x+x=360^o=>x.\left(3+4+2+1\right)=360^o\)=>\(10x=360^o=>x=36^o\)

Vậy x=36^o

Answer 4

Ta có: \(\widehat{M}+\widehat{N}+\widehat{P}+\widehat{Q}=360^0\) (định nghĩa)

\(\Rightarrow3x+4x+x+2x=360^0\)

\(\Rightarrow10x=360^0\Rightarrow x=36^0\)

\(\Rightarrow\left\{{}\begin{matrix}\widehat{M}=3.36^0=108^0\\\widehat{N}=4.36^0=144^0\\\widehat{P}=36^0\\\widehat{Q}=2.36^0=72^0\end{matrix}\right.\)
