An eight foot wire is attached to the tree and to a stake in the ground.
• From the top of a fire tower, a forest ranger sees his partner on the ground at an angle of depression of 40º.
If the tower is 45 feet in height, how far is the partner from the base of the tower, to the • Remember that the "angle of depression" is from a horizontal line of sight downward.
The angle of depression of the plane is 30 degrees, as shown in the picture.
The plane is currently 10,000 feet above the ground and it's not quite over the runway yet.
We know that the plane is 10,000 feet up, so we can draw a triangle with the plane at one point.
We know that w is 90 degrees, which means that angle z must be 30 degrees.
Trigonometry's connection to measurement places it in the learner's manuals for a wide variety of professions.
Carpenters, construction workers, designers, architects, and engineers, to name a few, deal with measurements, and as such, they deal with triangle measures, or trigonometry.
You'll also learn how to solve problems related to angles of elevation and depression using basic trigonometric relationships Quick!
