Each interior angle in a polygon is (n-2)×180 ÷n
(12-2)×180/12
I always recommend mathway for math because you plug in formula then it gives you the answer then if you sign up for it you can see how. <span>The absolute value of a number is the distance of a number from zero on the number line. Absolute value is always positive, since a distance is non negative. Essentially, if you want the absolute value of a non negative number, it's just that number.and when is solved in the correct formula is 1 and -1 and since it has to be positive the answer is 1</span>
If the first bird is on top of the bird watcher and the height of the tree is the same, then we form a right triangle with right angle on the second bird.
We can solve the angle of depression by trigonometric functions. So,sin θ = 29.7 / 42.1θ = sin-1 (29.7/42.1)θ = 44.87°
Therefore, the angle of depression of the second bird and the bird watcher is 44.87°.
