Answer:
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
So it would look like this: y + 8 = -4(x - 2)
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The length of the wire is 81.5 meters.
<h3>What is Sine (Sinθ)?</h3>
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
The length of the tower is 80 meters, while the angle of elevation is 79°. Therefore, the length of the wire will be the hypotenuse of the triangle. Therefore, the length of the wire is,
Sin(θ) = Perpendicular/Hypotenuse
Sin(79°) = 80 meter/Length of the wire
Length of the wire = 81.4973 ≈ 81.5 meters
Hence, the length of the wire is 81.5 meters.

Answer:
80 ft2
First let's find the total area of the wall: 12 x 8 = 96. Then, we need to subtract out the window. To find the area of the wall, we'll need to find the area of the window and subtract it from the total area of the wall: 4 x 8 = 32 | 96 - 32 = 64. However, I am assuming the height of the window is 8 feet. If the window is 1 foot tall, the answer is 92 feet. If the window is 4 feet tall, the answer is 80 feet.
(The first and last answers are incorrect) As there is no picture provided, as I am assuming there is a picture, please follow my instructions left for you above as to what the answer would be depending on the height of the window.
