Question

You are standing in a 50 meters from a siloThe angle of elevation to the top is need to of to the at which you are standing. What is the shortest length of rope used?

Answer 1

Answer:

77.786 m

Step-by-step explanation:

The shortest length of the rope used cabnbe obtained using trigonometric relation :

Shortest length of the rope = hypotenus

Using the relation :

Cos θ = Adjacent / hypotenus

Adjacent = 50 ;θ = 50°

Cos 50 = 50 / hypotenus

Hypotenus = 50 / cos 50

Hypotenus = 77.786 m
