Can you use the trigonometry table with the sin cos and tg values?
If you can it's easy...
All you need to do is sin64 = y/hipotenuse
It is 0,898794 = y/18
y = 0,898794 x 18
y = 16,178292
And to find x you just do cos64 = x/hipotenuse
0,438371 = x/18
x = 0,438371 x 18
x = 7,890678
If you can't use the trigonometry table then I have to think more...
Hope I helped you...

Post above...
To do a cosine law you usually need 2 sides and 1 angle..
But it's not neccessary at all..
It's a triangle with a 90 degrees angle...
