Answer:
Step-by-step explanation:
The angle of elevation
It is 
away from the point.
If we imagine a right triangle having an angle 
.
Hypotenuse
, Opposite=Height from sea level
Twelve point nine plus eight equals twenty point nine (12.9 + 8 = 20.9)

Answer:
Option B
y coordinate is 0
Step-by-step explanation:
We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.
X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0
To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.
Thus we have along x axis, y values to be 0
Hence any point on x coordinate will be of the form (a,0) where a can be any real number
So option B is right
