Evaluate trigonometric functions in the problem

$$\frac{{(80 - 68)} / 2}{0.1227845609029046}$$

Tuhia te \frac{\frac{80-68}{2}}{0.1227845609029046} hei hautanga kotahi.

$$\frac{80-68}{2\times 0.1227845609029046}$$

Tangohia te 68 i te 80, ka 12.

$$\frac{12}{2\times 0.1227845609029046}$$

Whakareatia te 2 ki te 0.1227845609029046, ka 0.2455691218058092.

$$\frac{12}{0.2455691218058092}$$

Whakarohaina te \frac{12}{0.2455691218058092} mā te whakarea i te taurunga me te tauraro ki te 10000000000000000.

$$\frac{120000000000000000}{2455691218058092}$$

Whakahekea te hautanga \frac{120000000000000000}{2455691218058092} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
