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

Answer: =17x
Step-by-step explanation: hope this help, hope you understand it too.
Let's simplify step-by-step.
2x+5x+10x
Combine Like Terms:
=2x+5x+10x
=(2x+5x+10x)
=17x
Use the equation 459/x=85/100. then you cross multiply 459 and 100 to get 45900. after that you divide 45900 by 85 to get x=540
