we know that
The formula to calculate the sum of the internal angles of a polygon is equal to
where
n is the number of sides
In this problem we have
substitute
Find the measure of each internal angle
Divide the sum of the internal angles by the number of sides
The value of x is half the measure of internal angle
so
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
