A 70-foot wire attached to the top of a building is anchored to the ground 20 feet from the base of the building. Which value is
JulijaS [17]

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 = \dfrac{\textrm Base}{\textrm Hypotenuse}

Or, Cos Ф =  \dfrac{\textrm OA}{\textrm OB}

or, Cos Ф =  \dfrac{\textrm 20}{\textrm 70}

Or, Cos Ф =  \dfrac{\textrm 2}{\textrm 7}

∴  Ф = Cos^{-1}(\frac{2}{7})

I.e Ф = 73.39°

Now in radian ,

∵ 180° = \pi radian

∴ 73.39° = \frac{\pi }{180} × 73.39°

             =  \frac{3.14 }{180} × 73.39° = 1.280 radian

Hence The the angle which the wire make with the ground is 1.280 radian . Answer

barxatty [35]
PH is calculated by the negative logarithm of the hydrogen concentration in a solution. Therefore, the pH in this case is:

pH = -log (0.0000006)
pH = 6.22

Therefore the correct answer among the choices is the last option, pH of 6 with a color pink.
