If you use the angle with 32 deg you would have Opposite = 25 and
Hyp = x
when you get that you can use a + b = c
A = 25
B = RS
C = the hyp you found earlier
Im not sure on the second one because I don't know if you can use S C T or not without a Right angle its been too long for me if i have time ill figure out how to do it and help you out.
