Kua tāruatia ki te papatopenga
\frac{0.898794046299167}{39} = \frac{0.4383711467890774}{a}
Evaluate trigonometric functions in the problem
a\times 0.898794046299167=39\times 0.4383711467890774
Tē taea kia ōrite te tāupe a ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 39a, arā, te tauraro pātahi he tino iti rawa te kitea o 39,a.
a\times 0.898794046299167=17.0964747247740186
Whakareatia te 39 ki te 0.4383711467890774, ka 17.0964747247740186.
a=\frac{17.0964747247740186}{0.898794046299167}
Whakawehea ngā taha e rua ki te 0.898794046299167.
a=\frac{170964747247740186}{8987940462991670}
Whakarohaina te \frac{17.0964747247740186}{0.898794046299167} mā te whakarea i te taurunga me te tauraro ki te 10000000000000000.
a=\frac{85482373623870093}{4493970231495835}
Whakahekea te hautanga \frac{170964747247740186}{8987940462991670} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
