Assume that y varies directly with x, then solve

To find the answer, first find y if x is 1. So, divide 9.9 by itself and -6.6 by 9.9. Then you get y=-0.666... when x=1. Then multiplty both by 6.6. You will get y=-4.4 when x=6.6.

The answer remains as is, or you could do it this way: 1(9 + 8b²).

By first calculating the size of angle LMN, calculate the area of triangle MNL. You must show all your working.

RSB [31]

Answer:

m(∠LMN) = 67.44°

Area of ΔMNL = 16.66 square units

Step-by-step explanation:

By applying Sine rule in the ΔLMN,

$\frac{\text{Sin}M}{\text{NL}}=\frac{\text{Sin}N}{\text{ML}}$

$\frac{\text{Sin}M}{7.2}}=\frac{\text{Sin}38}{\text{4.8}}$

SinM = $\frac{\text{Sin}38\times 7.2}{4.8}$

SinM = 0.9235

M = $\text{Sin^{-1}}(0.9235)$ $\text{Sin}^{-1} (0.9235)$

M = 67.44°

m(∠M) + m(∠N) + m(∠L) = 180°

67.44 + 38 + m(∠L) = 180°

m(∠L) = 180 - 105.44

m(∠L) = 74.56°

Area of ΔMNL = $\frac{1}{2}(\text{ML})(\text{NL})\text{Sin}(74.56)$

= $\frac{1}{2}(4.8)(7.2)(0.96391)$

= 16.66 square units
