PLS HELP A support wire is needed to help stabilize a telephone pole. If the wire is to be attached at the top of the 30-foot telephone pole and it must be anchored to the ground 40 feet from the base of the telephone pole, what is the length of the support wire?

70 feet

Step-by-step explanation:

idk bruv

We need to find the height upto which the guy wire is connected to the pole which is

x

To find that, we can use a simple trigonometry function

If you know a little trigonometry, you can say that,

sin

(

θ

)

=

Opposite

Hypotenuse

The opposite side of

60

∘

is

x

. And the hypotenuse is

40

So,

→

sin

(

60

∘

)

=

x

40

Using the unit circle, we can find that

→

√

2

2

=

x

40

→

x

=

√

⋅

40

⇒

=
