Radicals:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number.

Answer:
B
Step-by-step explanation:
Since the triangle is right use the tangent ratio to find x
tan22° = =
Multiply both sides by x
x × tan22° = 203 ( divide both sides by tan22° )
x = ≈ 502.5 m → B
