Question

Giải nhanh giúp mik vs ạ

Answer 1

1: Ot nằm giữa hai tia OA và OB

=>\(\widehat{tOA}+\widehat{tOB}=\widehat{AOB}\)

=>\(\widehat{tOB}+38^0=75^0\)

=>\(\widehat{tOB}=75^0-38^0=37^0\)

2: tia Ax nằm giữa hai tia AB,AC

=>\(\widehat{xAB}+\widehat{xAC}=\widehat{BAC}\)

=>\(\widehat{xAB}+45^0=120^0\)

=>\(\widehat{xAB}=120^0-45^0=75^0\)

3: tia Oz nằm giữa hai tia Ox và Oy

=>\(\widehat{xOz}+\widehat{yOz}=\widehat{xOy}\)

=>\(\widehat{yOz}+50^0=150^0\)

=>\(\widehat{yOz}=150^0-50^0=100^0\)

4: tia Om nằm giữa hai tia Ot,Oy

=>\(\widehat{mOy}+\widehat{mOt}=\widehat{yOt}\)

=>\(\widehat{mOt}+45^0=90^0\)

=>\(\widehat{mOt}=45^0\)
