Answer

  • 23.32°
  • x=4637.16 feet
  • y=1999.8 feet  
  • Explanation

Sketch a triangle ABC, where A is at the apex(top) and BC is the base.Let side AB=5050 feet and BC=6000feet.Drop a perpendicular line from A to BC at O to represent distance y and OB is distance x.

Point A = your location

Point B=First tower and Point C is the second tower.

To calculate the angle in degrees we use law of cosines,

2420²=5050²+6000²-(2)(5050)(6000)(cosB)

B=23.32° is the angle in question

Secondly, we find value of x

CosB=x/5050

X=4637.16feet, the position east of the tower

Thirdly, we calculate y

SinB=y/5050

0.39599=y/5050

y=1999.77

y=1999.8 feet , the position north of the tower
