Answer:
c squared - a squared = b squared
Step-by-step explanation:
Since a squared + b squared = c squared
With these values it would equal 14 squared - 7 squared = c squared
Then after you find c squared, find the square root of it and there you have go your answer!
2.21 x 10^17 and the answer is 2.21e+17
The answers to that question is 75 degreey
Answer:
if you are adding the hours in total it is 6 hours but if you are adding the miles it is 340 miles
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.
