Find the equation of the line that passes through the point (−3, −4) and is parallel to the line that passes through the points

Dimas [21]

Answer:

$y = -\frac{1}{3}x - 5$

Step-by-step explanation:

To write the equation of a line use the point slope formula $y - y_1 = m(x-x_1)$ . Find m by using the slope formula with the points.

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{1--3}{-5-7} =\frac{4}{-12} =-\frac{1}{3}$

Since the line is parallel, it will have the same slope.

Substitute m = -1/3 and (-3,-4).

$y --4 = -\frac{1}{3}(x --3)\\y + 4 = -\frac{1}{3}(x+3)\\y +4 = -\frac{1}{3}x - 1\\y = -\frac{1}{3}x - 5$

Calculate the side lengths a and b to two decimal places

muminat

Answer:

Option (D)

Step-by-step explanation:

In the picture attached,

An obtuse angle triangle ABC has been given.

By applying Sine rule in the triangle,

$\frac{\text{SinB}}{b}=\frac{\text{SinA}}{a}=\frac{\text{SinC}}{c}$

Since, m∠A + m∠B + m∠C = 180°

45° + 110° + m∠C = 180°

m∠C = 180°- 155° = 25°

$\frac{\text{Sin110}}{b}=\frac{\text{Sin45}}{a}=\frac{\text{Sin25}}{7}$

$\frac{\text{Sin110}}{b}=\frac{\text{Sin45}}{a}=0.060374$

$\frac{\text{Sin110}}{b}=0.060374$

b = $\frac{\text{Sin110}}{0.060374}$

b = 15.56

b ≈ 15.56

$\frac{\text{Sin45}}{a}=0.060374$

a = $\frac{\text{Sin45}}{0.060374}$

a = 11.712

a = 11.71

Therefore, Option (D) will be the answer.
