The steps to derive the quadratic formula are shown below:

prohojiy [21]

Answer:

$\huge\boxed{\sf Option \ B}$

Step-by-step explanation:

$\displaystyle x^2+\frac{bx}{a} =\frac{-c}{a}$ --------------------(1)

to find the b² for the expression on the left.

Take the expression

$\displaystyle x^2 + \frac{bx}{a}$

<u>We can also write it as:</u>

$\displaystyle (x)^2 + 2(x)(\frac{b}{2a} )$

According to the formula $a^2+2ab+b^2$ , the b of this expression is $\displaystyle \frac{b}{2a}$ . So,

b² will be:

$\displaystyle =(\frac{b}{2a} )^2\\\\=\frac{b^2}{4a^2}$

So, we will add $\displaystyle \frac{b^2}{4a^2}$ to both sides in Eq. (1)

For STEP 4, the equation will become:

$\displaystyle x^2+\frac{bx}{a} + \frac{b^2}{4a^2} = \frac{-c}{a} + \frac{b^2}{4a^2}$

$\rule[225]{225}{2}$

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: $\displaystyle x \approx 38.2 ^{\circ}$
