You sight the top of a 50-ft tree from a point on the ground 50 ft from the base of the tree. What is the angle of elevation?

The angle of elevation of the top of a tree from a point 50 feet from it's base is 30 degrees .

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
