Kua tāruatia ki te papatopenga
x\times 180=45\pi
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 45x, arā, te tauraro pātahi he tino iti rawa te kitea o 45,x.
180x=45\pi
He hanga arowhānui tō te whārite.
\frac{180x}{180}=\frac{45\pi }{180}
Whakawehea ngā taha e rua ki te 180.
x=\frac{45\pi }{180}
Mā te whakawehe ki te 180 ka wetekia te whakareanga ki te 180.
x=\frac{\pi }{4}
Whakawehe 45\pi ki te 180.
x=\frac{\pi }{4}\text{, }x\neq 0
Tē taea kia ōrite te tāupe x ki 0.
