Graph the point there.
Draw a picture of the problem.
let ∅ be the angle formed in the first quadrant such that its y coordinate is twice its x coordinate.
The lengths are denoted 2a and a.
Joining the point (0, 0) to the point described, in the first quadrant, we have a right triangle with side lengths
, where 
is the hypotenuse, found by the Pythagorean theorem.
sin∅=opposite side/hypotenuse=
Now consider the reflection of the red line segment with respect to the x-axis, the ratio of the distances described still holds. Since here we are in the fourth quadrant, the sine is negative, so sin is

Answer:
22m
Step-by-step explanation:
Let height of flagpole=h
AB==17 m
(1 degree= 60 minute)
We have to find the approximate height of the flagpole.
In triangle CDA,
In triangle CDB,
Substitute the value
Substitute the value
Hence, the height of the flagpole=22 m
