You’re trying to find x which is the side opposite to the angle. You’re given the adjacent angle. To find the variable, you use tangent. So you plug in tan(x)= opposite/adjacent. In this case it would be tan(27)=x/15. Then you multiply both sides by 15 to be 15(tan(27))=x which is 7.6=x

Step-by-step explanation:

first plug in your numbers

a*2+ b*2= c*2

12*12= 144

7*7=49

144+49= 193

square root of 193: 13.89244399

rounded to nearest tenth is 13.9

QuestionIn PQR, sin P = 1/3, sin R = 2/3,and p = 9. Find the side length r.

mamaluj [8]

Lets draw our triangle:

Lets use the "Law of Sines" to find our side r:

$\frac{p}{\sin P}=\frac{r}{\sin R}\rightarrow\frac{9}{\frac{1}{3}}=\frac{r}{\frac{2}{3}}\rightarrow9\times\frac{3}{1}\times\frac{2}{3}=r\rightarrow r=18$

So r=18
