A vertical pole is supported by two ropes staked to the ground on opposite sides of the pole. One rope is 8 meters long, and the

aniked [119]

Establish two right triangles, both with the height of the pole, h.

Call x the distance from the pole to one stake. Then the distance from the other stake to the pole is 6 -x.

Apply Pytagora's equation to both triangles.

1) h^2 = 7^2 - x^2

2) h^2 = 8^2 - (6-x)^2

Eaual 1 to 2

7^2 - x^2 = 8^2 - 6^2 +12x -x^2

12x = 7^2 -8^2 +6^2 = 49 -64 + 36 = 21

x = 1.75

Substitue x-value in 1

h^2 = 49 - (1.75)^2 = 45.94

h = sqrt(45.94) = 6.78

Answer: option d.

Help will mark brainliest and give points

Elodia [21]

Answer:

I will gladly assist you with your problem! (see explanation)

Step-by-step explanation:

Suppose that the tower's height is t and that the necessary distance is x.

To determine the value of t, use comparable triangle ratios:

$t / 10 = (9 + 3) / 3t / 10 = 4t = 40 feet$

Use Pythagorean Theorem to find the value of x:

$x^{2} =40^{2} +(9+3)^{2} \\x^{2} =1600+144\\x^2=1744\\x=\sqrt{1744} \\x= 42 feet$ (answer is rounded)

(I hope this helps solve your problem )

g the value of tan(-150) is because -150 is in quadrant the reference angle is and the exact value of tan (-150) is

never [62]

Answer:

Step-by-step explanation:

Given the expression tan (-150), from trigonometry identity, tan(-θ) = -tanθ

Hence tan (-150) = - tan 150

First is to find the value of tan 150.

tan 150 = tan (180-30)

tan (A+B) = (tan180 - tan30)/1+tan180tan30

tan (180-30) = (0 - 1/√3)/1+0(1/√3)

tan (180-30) = -1/√3/1

tan (180-30) = -1/√3

Since tan 150 = -1/√3

-tan 150 = -(- 1/√3)

-tan 150 = 1/√3

Since -tan 150 = tan (-150) = 1/√3

Hence the exact value of tan (-150) is 1/√3
