Whakaoti i te 0.5/x=sin105^circ/20

$$\frac { 0.5 } { x } = \frac { \sin 105 ^ { \circ } } { 20 }$$

Whakaoti mō x

$$x = \frac{100000000000000000}{9659258262890683} = 10\frac{3407417371093160}{9659258262890684} \approx 10.352761804$$

Evaluate trigonometric functions in the problem

$$\frac{0.5}{x} = \frac{0.9659258262890683}{20}$$

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 20x, arā, te tauraro pātahi he tino iti rawa te kitea o x,20.

$$20\times 0.5=x\times 0.9659258262890683$$

Whakareatia te 20 ki te 0.5, ka 10.

$$10=x\times 0.9659258262890683$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x\times 0.9659258262890683=10$$

Whakawehea ngā taha e rua ki te 0.9659258262890683.

$$x=\frac{10}{0.9659258262890683}$$

Whakarohaina te \frac{10}{0.9659258262890683} mā te whakarea i te taurunga me te tauraro ki te 10000000000000000.

$$x=\frac{100000000000000000}{9659258262890683}$$
