Look up the law of sines, I suggest Khan Academy. It is better if you know how to do it, it is very useful.
4 Is the answer since 4 is x 4+4 is 8 8-4 is 4 :)
7x +16 < -5(4 - 5x)....given
7x + 16 < -20 + 25x....distributive property
16 < -20 + 18x ... subtraction property
16 + 20 < 18x.....addition property
36 < 18x
36/18 < x.....division property
2 < x
