Answer:

Explanation:

The only angle we are given directly inside that triangle is angle R, 87 degrees. We can use the fact that the exterior angle at T is 92, so the interior angle is 180 - 92 = 88. Now we can find angle S: 180 - 87 - 88 = 5. So angle S = 5 degrees. The Law of Sines can be used now to find the length of SR:


(sin5)/(950) =(sin88)/(x)

Cross multiply to get

x sin5 = 950 sin88 and


x=(950sin88)/(sin5) so

x = 10,893 km
