Trig/geometry help (triangles/finding sides)

I have to find side 'R'
L = 6.10 meters, theta = 36.9 degrees, and phi = 53.1 degrees.

I don't see any way I can attempt this, I'm very rusty with my trig. We have a known side and a right angle, but I don't see how I can make any other angles (since we only have one side I'm assuming I need to get an angle somewhere
