We have a right triangle, NSS....we know an angle and an opposite side to the angle
And we are looking for the side adjacent to the angle, x
[The adjacent side is the side next to the angle.....but not the hypotenuse....[ the side opposite the right angle]
The tangent of an angle = ratio of the its opposite side to its adjacent side....so
tan (17°) = 200 / x multiply both sides by x
x * tan (17”) = 200 divide bothsides by tan (17°)
x = 200 / tan (17°) = 654 ft
Hope that helps, NSS....
