Answer:
Distance between the person and the plane is 12 miles
Step-by-step explanation:
From the figure attached,
An airplane is flying at an altitude AB = 6 miles.
An observer is standing at point C from where he observes the plane at an angle of elevation θ
Therefore, sinθ = 
sinθ = 
AC = 
AC = 6cosecθ
If angle θ = 30°
Then AC = 6cosec30
AC = 6×2
AC = 12 miles
Therefore, distance between the person and the plane is 12 miles.
Since the perimeter of the square is 28ft, the side length of the square is 7ft.
Hence, the area of the square is 49 square feet.
Answer:
just go to math leaks the website and then click on geometry and you should find the 2009 textbook with all the answers
Step-by-step explanation:
Multiply both sides by 8 to cancel out the fraction. this comes to 24<5+p. add 5 to both sides. answer: 29<p. Hope this helps!!
E= 9 because you have to distribute -3.6 to E and -4
