Answer:
The the angle which the wire make with the ground is 1.280 radian .
Step-by-step explanation:
Given as :
The length of the wire attached to the top of building = OB = 70 foot
The distance of wire anchored from base of ground = OA = 20 feet
Let the angle made by wire en and ground = Ф
Now from , In Triangle AOB
Cos angle =
Or, Cos Ф =
or, Cos Ф =
Or, Cos Ф =
∴ Ф =
I.e Ф = 73.39°
Now in radian ,
∵ 180° = radian
∴ 73.39° = × 73.39°
= × 73.39° = 1.280 radian
Hence The the angle which the wire make with the ground is 1.280 radian . Answer
