the sum of angles in a triangle is 180

missing angle + 90 + 51 = 180

missing angle = 180 - 141

missing angle = 39 degrees.

in the triangle,


(x)/(200)=\tan 51

x = 200 tan51

x = 200 * 1.234

x = 246.97 ft apporx 247 ft

'so the length x = 247 ft

that is greater than 200

so the answer is

x > 200 ft
