Answer:
The ratio of student that completed their homework to the students who didn't complete their homework is 9:6 = 9 /6
Step-by-step explanation:
9 of 15 students completed their homework .The ratio of students who completed their homework to the ratio that didn't complete their's can be calculated below
The total number of student that was given the homework is 15 . Out of this 15 students only 9 of the students completed their homework. The remaining student out of the 15 didn't complete their's.
The remaining number of student that didn't complete their homework is 15 - 9 = 6 .
Therefore,
The ratio of student that completed their homework to the students who didn't complete their homework is 9:6 = 9 /6
The ratio can be further reduced to 3/2
Answer:
50
Step-by-step explanation:
because the total number of traingle =180 so we have 15 and 35 which equal 50 and the inside angle = 130 and x = 50

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.
