The solution is (-3,5)
The solution to a system of linear equations is just the intersection point
First you have to add and subtract everything on both sides that have common terms.
then becomes
Then you subtract 15w from each side and get
Divide each side by -9 and get
which we can simplify by 3
Answer:
angle = arc tangent(6/x)
for x=2 -> angle = 71.565°
Step-by-step explanation:
To find the relation of the distance x and the angle of elevation that you are seeing the airplane, we should use the tangent relation of the angle. The opposite side of the angle is the altitude of the airplane, and the adjacent side of the angle is the distance x.
So we have that:
tangent(angle) = 6/x
angle = arc tangent(6/x)
If we have the value of x = 2, the angle will be:
angle = arc tangent(6/2) = arc tangent(3)
angle = 71.565°
