Pls work out as t-ratios.

a telegraph pole stranding on level ground is 9 meter tall and is supported by 2 wire guys attached to the top of the pole. each guy makes an angle of 28° with the top of the pole. how far away from the foot of the pole are the guys anchored?

16.93 m

Step-by-step explanation:

The triangle for the given scenario is shown below.

From the triangles and ,

AB is the pole height, BC or BD is the distance of either of the wire guys from the foot of pole, and or is the angle that each either of the guys make with the top of pole.

Let the distance of either of the wire guys from the foot of pole be .

Now, consider .

Given: AB = 9 m, BC = , and °.

Using tan ratio of the angle C, we get

Therefore, 16.93 m away from the foot of the pole are the guys anchored.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
