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.

3y + y = 4y
answer: 4y
Skittles come in packages of 10. Arthurate 25 Skittles. How many whole boxes didhe eat and how many Skittles does he haveleft?
Answer: He ate 2 and 1/2
3*3/5=1.8 but, idk how to represent that as a unit fraction
Since this is an arithmetic sequence it would just be 8 x 24 which is 192
