Which expression will help you find the measure of angle R?
sin R/3.5 cm = sin 70º/6.2 cm
R = arc sin 3.5/6.2 cm
sin R/6.2 cm = sin 70º/3.5 cm
(3.5 cm)(sin R) = (6.2 cm)(sin 70º)
this is the second time you posted this question - I know because I just answered it.
Please do not repost until the original question goes to the second page.
Even then it would be polite for you to say that you are reposting.
Using the Law of Sines.....
