If r(x) = 3x – 1 and s(x) = 2x + 1, which expression is equivalent to (r/s)<br>6)?

Flauer [41]

$\bf \begin{cases} r(x)=3x-1\\ s(x)=2x+1\\ \cline{1-1} \cfrac{r(x)}{g(x)}=\left( \cfrac{r}{s} \right)(x) \end{cases} \\\\[-0.35em] ~\dotfill\\\\ r(6)=3(6)-1\implies r(6)=17~\hfill s(6)=2(6)+1\implies s(6)=13 \\\\[-0.35em] ~\dotfill\\\\ \left( \cfrac{r}{s} \right)(6)\implies \cfrac{r(6)}{s(6)}\implies \cfrac{17}{13}$

Find the measure of angle C of a triangle ABC if measure of angle a = 24 degrees and measure of angle b = 130 degrees

pickupchik [31]

26 degrees.
For any regular convex polygon with n sides, the sum of all its interior angles will be (n-2)*180.
Using this we know that the sum of all the angles will be 180 degrees.
24+130+x=180
154+x=180
x=26
