Answer:
The height of the monument is 119.17 feet
Step-by-step explanation:
Let the wire , monument and ground be represented by a right angled triangle then the wire can be taken as the hypotenuse or the resultant vector whose magnitude is determined by R Cos ∅
The monument will represent the perpendicular so the height of the monument will be given by
Perpendicular= Base Tan ∅
the base is 100 feet ∅ is 50 °
Perpendicular= 100 tan 50°
Perpendicular= 100(1.1917)
Perpendicular= 119.17 feet
