An observer in the top of a lighthouse determines that the angles of depression to two sailboats directly in line with the lighthouse are 3.5º and 5.75º. If the observer is 125 feet above sea level, find the distance between the boats. Round to the nearest tenth.

step-by-step explanation:

eve and marks ratios are equivalent

step-by-step explanation:

what graph

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
