The observation tower has a height of 105 m above sea level. The ship is aimed at a depth angle of 1° 49' from the tower. How far is the ship from the base of the tower?

Correct answer:

x =  198.6954 km

Step-by-step explanation:

h=105 m A=1/60+49/3600=36001090.0303   tanA=h:x  x1=h/tanA=h/tan0.030277777777778° =105/tan0.030277777777778° =105/0.000528=198695.43706 m  x=x1 km=x1:1000  km=198695.4371:1000  km=198.695 km=198.6954 km
