Can someone tell me the answer to this question

If these two lines are parallel, they would have the same gradient.

Since Gradient = Rise / Run,

8 / -12 : -4 / 1

These two ratios are obviously not the same, so we can conclude the lines are not parallel.

Can someone help me solve (a) and (c) pls. Thanks

Answer:

Area of ABCD = 959.93 units²

Step-by-step explanation:

a). By applying Sine rule in the ΔABD,

$\frac{\text{SinA}}{46}=\frac{\text{Sin}\angle{DBA}}{35}$

$\frac{\text{Sin110}}{46}=\frac{\text{Sin}\angle{DBA}}{35}$

Sin∠DBA = $\frac{35\times \text{Sin}(110)}{46}$

m∠DBA = $\text{Sin}^{-1}(0.714983)$

m∠DBA = 45.64°

Therefore, m∠ADB = 180° - (110° + 45.64°) = 24.36°

m∠ADB = 24.36°

c). Area of ABCD = Area of ΔABD + Area of ΔBCD

Area of ΔABD = AD×BD×Sin( $\frac{24.36}{2}$ )

= 35×46Sin(12.18)

= 339.68 units²

Area of ΔBCD = BD×BC×Sin( $\frac{59.92}{2}$ )°

= 46×27×(0.4994)

= 620.25 units²

Area of ABCD = 339.68 + 620.25

= 959.93 units²
