Step-by-step explanation:
Given: An 757 passenger jet at the height of 3900 feet from the ground means vertical height = 3900 feet.
Angle of descent to the airport in Washington,D.C. is 6 degrees.
To find: Horizontal distance the plane will cover to reach the run way.
Solution: As we know tan ∅ =
Then tan 6° =
0.105 =
x =
x = 37106 ft
Answer:
see explanation
Step-by-step explanation:
- 17 = - 2 - x ( add 2 to both sides )
- 15 = - x ( multiply both sides by - 1 )
15 = x
-----------------------------------------------------
- 9 = - 15 ( add 9 to both sides )
= - 6 ( multiply both sides by 3 to clear the fraction )
x = - 18
--------------------------------------------------------
- 3 = 2 + ( subtract 2 from both sides )
- 5 = ( multiply both sides by 3 to clear the fraction )
- 15 = x
