A person is standing 118 ft from the base of the Washington monument. The person measures the angle between the ground and the top of the monument to be 78 degrees. Find the height h of the Washington monument to the nearest foot.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

it is b)

hope this : )
