For this case we can use the law of the sine to solve the problem.
We have then:
[tex]5 / sine (68) = 5 / sine (x)
[/tex]
From here, we clear the value of x.
We have then:
[tex]sine (x) = (5/5) * (sine (68))
[/tex]
Rewriting we have:
[tex]sine (x) = (1) * (sine (68))
sine (x) = sine (68)
x = arcsine (sine (68))
x = 68[/tex]
Answer:
The angle R is given by:
x = 68 degrees
option B
