Let's solve your equation step-by-step.

−66.17738=6.618(4.3x+1.1)−7.1(x−6.8)

<em>Step 1: Simplify both sides of the equation. </em>

−66.17738=6.618(4.3x+1.1)−7.1(x−6.8)

−66.17738=(6.618)(4.3x)+(6.618)(1.1)+(−7.1)(x)+(−7.1)(−6.8)(Distribute)

−66.17738=28.4574x+7.2798+−7.1x+48.28

−66.17738=(28.4574x+−7.1x)+(7.2798+48.28)(Combine Like Terms)

−66.17738=21.3574x+55.5598

−66.17738=21.3574x+55.5598

<em>Step 2: Flip the equation. </em>

21.3574x+55.5598=−66.17738

<em>Step 3: Subtract 55.5598 from both sides</em>.

21.3574x+55.5598−55.5598=−66.17738−55.5598

21.3574x=−121.73718

<em>Step 4: Divide both sides by 21.3574. </em>

21.3574x

21.3574

=

−121.73718

21.3574

<u>x=−5.7</u>

How did he get from 3^-16/3/3^-8/3 to 0.00285333857/0.00285333857??? (The circled part) Because when I put it in the calculator
seropon [69]

Step-by-step explanation:

\frac{ {3}^{ -  \frac{16}{ 3} } }{ {3}^{  - \frac{ 8}{3} } }  =  \frac{0.002853338}{0.05341665075}

I think, he made a mistake because the exponents have different values but then if you'll look at his results, he just wrote the same thing. If you want, you could post the original problem, and I'll solve it for you :)

Will give medal to best answer!

We have two sides and one angle opposite to one of the known sides.

Begin with applying the Law of Sines to find angle A:
\frac{sin A }{a} = <span>\frac{sin C }{c}

Then, solve for sin A:
</span>sin A = \frac{a sinC}{c}

Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17

We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
