Answer:
c
Step-by-step explanation:
If you are looking to turn it into an expression:
1/3w+16
or it could possibly be (if you are looking at inequalities):
1/3w<16
Knowing that a square gives the optimum area;
120=s²
√120=s
√2×2×2×5×3=s
2√2×3×5=s
2√30=s
Therefore, the length should be ≈10.95"
Hope I helped :)

Answer:
1.68 km
Step-by-step explanation:
You want the horizontal distance (on the ground) from beneath the helicopter to the vertex of the 37 degree angle. The hypotenuse is given and is 2.1 km.
We want to find the horizontal distance when we already know the angle and the hypotenuse.
That horizontal distance could be called 'x.' Then:
x/r = adj/hyp = cos 37 degrees, which becomes adj = (2.1 km)cos 37 degrees, which is found using a calculator: adj = (2.1 km)(0.7987) = 1.68 km
