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:
Total amount pay by Ben = $82.27 (Approx.)
Step-by-step explanation:
Given:
2 Shirts = $16 each
3 pairs of socks = $2.50 each
1 pair of jeans = $37.75 each
Sales tax = 6.5%
Find:
Total amount pay by Ben
Computation:
Total amount for shirts = 2 x 16
Total amount for shirts = $32
Total amount for socks = 3 x 2.50
Total amount for shirts = $7.50
Total amount before tax = $32 + $7.50 + $37.75
Total amount before tax = $77.25
Total amount pay by Ben = Total amount before tax[1+tax]
Total amount pay by Ben = 77.25[1+6.5%]
Total amount pay by Ben = $82.27 (Approx.)
