first off, trig functions are just numbers. they have no units (such as meters). Maybe those little m's are meant to be ° symbols. If sin(x) = 8/32, x = 14.48° did you visit the trig site I provided? http://www.rapidtables.com/calc/math

You can graph it, if you calc is a graphing calc. graph y=x^2+8x+5, where it crosses the x axis, is the solutions.
