State the side lengths to the nearest tenth and the measure of angle R to the nearest degree if the measure of angle S is 35 degrees and r=15

Question

I'm having an issue on this question, please help :)

Answer 1

If you have syou can use law of cosines. But usually you need three numbers to make any of these triangle problems work, two sides and an angle or two angles and a side? If RST is a right triangle that helps too.

 

Hope that helps!
