Answer:

x=-9

Step-by-step explanation:

M(slope)=y2-y1/x2-x1

m=-5-5/-9+9

m= -10/0

This means the slope is undefined. Whenever the slope is undefined, the line is vertical and is passing through the x-axis and parallel to the y-axis. Take the given coordinate (-9,5) and all you do is put x= -9. That's the equation of the line.

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

kiruha [24]

Answer:

y - 5 = (-5/6)(x - 2)

y - 5 = (-5/6)x + 10/6

y - 30/6 = (-5/6)x + 10/6

y = (-5/6)x + 20/3
