Answer:
Step-by-step explanation:
<em>The complete question is </em>
What is the length of line segment RS? Use the law of sines to find the answer. Round to the nearest tenth.
see the attached figure to better understand the problem
step 1
Find the measure of angle S
Applying the law of sines

substitute the given values

Solve for sin(S)

![S=sin^{-1}[sin(80^o)}{3.1}(2.4)]](https://tex.z-dn.net/?f=S%3Dsin%5E%7B-1%7D%5Bsin%2880%5Eo%29%7D%7B3.1%7D%282.4%29%5D)

step 2
Find the measure of angle Q
Remember that the sum of the interior angles in any triangle mut b equal to 180 degrees
so

substitute the given values
step 3
Find the length of segment RS
Applying the law of sines
substitute the given values
The answer are (1, 5) and (1, 3)
Answer:
x=17°
Step-by-step explanation:
The opposite angles, will always be the same. so the the angle across from 163° will be 163
so 163°-x°=180°
Because straight angles = 180°
You'd get x°=17°
Hope this helps :))
