You divide the 15x by the 124. I know it sounds weird because you'll get a decimal, but that is what you are supposed to do because 124 is not a factor of 5.

Add 19 to both sides. -15x-19+19=124+19.
Then, simplify which is -15x=143.
Third, divide both sides with -15. so Then it will look like this= -15x/-15=143/-15.
After that, you simplify which is - 143/15
so answer is - 143/15

Hope this helps!

What is m∠V ? Round only your final answer to the nearest tenth. 53.9º 56.1º 61.9º 70.0º The figure shows acute triangle U V W.

IrinaVladis [17]

The correct option is: 53.9°

Explanation

According to the below diagram, $\triangle UVW$ is acute triangle, in which $\overline{UV}= 7.6 inches, \overline{VW}= 8.6 inches$ and $\overline{WU}=7.4 inches$

If we apply cosine rule here, then we will get.....

$cos(V) = \frac{(UV)^2+(VW)^2 -(WU)^2}{2(UV)(VW)}$

Now, plugging the given values, we will get....

$cos(V)=\frac{(7.6)^2+(8.6)^2-(7.4)^2}{2(7.6)(8.6)}\\ \\ cos(V)= \frac{76.96}{130.72}=0.58873...\\ \\ V= cos^-^1(0.58873...)=53.932.... \approx 53.9 degree$

So, the measure of $\angle V$ is 53.9°

Since they are simmilar we will then have the following relationships.

$\frac{15}{10}=\frac{9}{x}$

Now, we solve for x, as follows:

$x=\frac{9\cdot10}{15}\Rightarrow x=6$

The expression goes along the lines of. 15 is to 10 what 9 is to x, with this as was done we solve for x and determine it's value, that since they keep proportionality.
