The answer is B
Step-by-step explanation:
The angle of elevation that the instruments have to record to be at the correct height is given as 79°
<h3>How to solve for the angle of elevation</h3>
We have 2x + 70 = 180
We have to find the value of x
2x = 110
x = 55
y/sin x = 225/sin70
This is the use of sine rule
From here we would have
y = 225(sinx/sin70)
Remember x = 55
y = 225(sin55/sin70)
y = 196.1378
tanθ = 1000/y
tan θ = 1000/196.1378
tanθ = 5.098
θ = tan⁻¹5.098
= 78.90°
Hence the conclusion is that the angle of elevation has to be 78.9 degrees for it to be at the correct height.

Answer:
D) 32.5 ft
Step-by-step explanation:
Here we have to use the trigonometric ratio.
We need to find the length of the hypotenuse.
We use sin ratio.
Sin 38 = Opposite / Hypotenuse
Here opposite = 20, Hypotenuse = Length of the six cars
sin 38 = 20 / length of the six cars
The length of six cars = 20 / sin 38
The length of the six cars = 32.48
Which is closest to 32.5 ft
Thank you.
