Answer: x = 9.0

Step-by-step explanation:
You can use the law of sines on any triangle in the Euclidean plane. For this we will say the following

6.9 / sin(50) = x / sin(90)

And we know that the sin(90) = 1. So we really have:

6.9 / sin(50) = x

Put that in a calculator and you’ll get x = 9.007. Round that to the nearest tenth to get 9.0.

Cheers.
