Answer:
<h2>I. 336 ft²</h2>Step-by-step explanation:
We have
two right triangle with legs 6ft and 8ft
one rectangle 8ft × 12ft
one rectangle 6ft × 12ft
one rectangle 10ft × 12ft
The formula of an area of a right triangle:
a,b - legs
Substitute:
The formula of an area of a rectangle:
l,w - length, width (dimensions of rectangle)
Substitute:
The Surface Area:

The plane will end up flying 5.02°.
The plan's speed relative to the ground will be 645.91 km/hr.
Solution:
Use the cosine formula,
Substitute the given values in the formula,
Taking square root on both sides, we get
R = 645.91 km/hr
This is the grouped speed of the aircraft.
To find θ use sine rule.
Do cross multiplication, we get
sin θ = 0.0875
θ = 5.02°
This is known as the drift angle and is the correction the pilot should apply to remain on course.
The heading is the direction the aircraft's nose is pointing which is
The track is the actual direction over the ground which is θ = 5.02°
An alternative method to this would be to separate each vector into vertical and horizontal components and add.
The resultant can be found using Pythagoras.
