Question 472707
the bamboo pole is 8 meters in length.
the distance from the tree is 3 meters.
the tree is perpendicular to the ground (assumed).
you have a right triangle with a hypotenuse of 8 and an adjacent side of 3.
you would use the cosine formula to find the angle.
cosine (angle) = adjacent / hypotenuse = 3/8 = .375
use your calculator to find the angle equals 67.97568716 degrees.
the cosine of 67.97568716 degrees = 3/8.
the arc cosine of 3/8 = 67.97568716 degrees.
