Law of Sines: $\displaystyle \frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}$

A, B, C are angle measures
a, b, c are leg lengths

Step-by-step explanation:

<u>Step 1: Identify</u>

A = 27°, a = 11

B = x°, b = 15

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute [LOS]: $\displaystyle \frac{sin(27^{\circ})}{11} =\frac{sin(x^{\circ})}{15}$
Cross-multiply: $\displaystyle 11sin(x^{\circ}) = 15sin(27^{\circ})$
Isolate <em>x</em> term: $\displaystyle sin(x^{\circ}) = \frac{15sin(27^{\circ})}{11}$
Isolate <em>x</em>: $\displaystyle x = sin^{-1}(\frac{15sin(27)}{11})$
Evaluate: $\displaystyle x = 38.2488 ^{\circ}$
Round: $\displaystyle x \approx 38.2 ^{\circ}$

Let the price at which she sells the hi-fi set be x ~

$\huge \bf༆ Answer ༄$

The Money that she lose at the end of 2 years :

$\sf \: 2500 - x$

Loss percentage is equal to :

$\sf \dfrac{2500 -x }{2500} \times 100 = 20$

$\sf \dfrac{2500 - x}{25} = 20$

$\sf2500 - x = 20 \times 25$

$\sf2500 - x = 500$

$\sf - x = 500 - 2500$

$\sf - x = - 2000$

$\sf x = 2000$

So, the money she end up getting after selling that hi-fi set is 2500, that is also the money She have at the end of the two years ~

Write the equation of a line with a slope of –1 and a y-intercept of –6.

vazorg [7]

For this case the generic equation of the line is given by:

$y = mx + b$

Where,

m: slope of the line

b: intersection with the y axis

For this case we have:

$m = -1\\b = -6$

Therefore, substituting values in the generic equation we have:

$y = -x - 6$

Answer:

The equation of the line is:

$y = -x - 6$

option 1
