Issolvi 2*90^circ+(m-2)*170^circ=(2pi-4)*90^circ

$$2 \times 90 ^ { \circ } + ( m - 2 ) \times 170 ^ { \circ } = ( 2 \pi - 4 ) \times 90 ^ { \circ }$$

Solvi għal m

$$m = \frac{18 \pi - 20}{17} \approx 2.149921633$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 2 u 90 biex tikseb 180.

$$180+\left(m-2\right)\times 170=\left(2\pi -4\right)\times 90$$

Uża l-propjetà distributtiva biex timmultiplika m-2 b'170.

$$180+170m-340=\left(2\pi -4\right)\times 90$$

Naqqas 340 minn 180 biex tikseb -160.

$$-160+170m=\left(2\pi -4\right)\times 90$$

Uża l-propjetà distributtiva biex timmultiplika 2\pi -4 b'90.

$$-160+170m=180\pi -360$$

Żid 160 maż-żewġ naħat.

$$170m=180\pi -360+160$$

Żid -360 u 160 biex tikseb -200.

$$170m=180\pi -200$$

Iddividi ż-żewġ naħat b'170.

$$\frac{170m}{170}=\frac{180\pi -200}{170}$$

Meta tiddividi b'170 titneħħa l-multiplikazzjoni b'170.

$$m=\frac{180\pi -200}{170}$$

Iddividi 180\pi -200 b'170.

$$m=\frac{18\pi -20}{17}$$
