Hello! Sin(54)=1200/x seems tough, but is easy to solve with a calculator. Solve it backwards
instead of dividing by x, multiply by x on both sides
xSin(54)=1200
Now, we divide 1200 by xSin(54)
1200/Sin(54) P.S When you get here and divide don't worry about the x, as when you solve it you will get the value.
x = 1483.281573
