Geometric reasoning can be used to measure distances both on earth and in space. surveyors on earth and astronomers both use the geometric technique of triangulation to determine the distances and sizes of remote objects. in order to determine the distance using the triangulation method, a few key geometric components must be known. once the baseline and the sightline angles are determined, then the distance can be calculated with simple geometric reasoning. in the figure below, label the essential components used to triangulate the distance to the tree located on the opposite side of the river (assume the baseline remains constant).
a. angle that decreases with increasing distance to the objectb. distance to objectc. right angled. baselinee. angle that increases with increasing distance to the object

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
