All of the rings of a ladder are parallel and the top rung is perpendicular to a side of the ladder. What conclusion can be reac

Ronch [10]

Perpendicular sides or lines meet at right angles. The conclusion that can be reached is that:

1. all of the rings are perpendicular to that side.

The statements in the question can be listed as:

Rings in the ladder are parallel
Top ring is perpendicular to the side of the ladder

From statements 1 and 2 above, we understand that;

All other rings in the ladder are parallel to the side ring

This means that the relationship between the top ring and the side of the ladder is the same as the relationship between other rings and the side of the ladder

i.e. the side rings are also perpendicular to the side of the ladder

Hence, the conclusion that can be reached is:

1. all of the rings are perpendicular to that side.

An aircraft is spotted by two observers who are 1000 feet apart. As the airplane passes over the line joining them, each observe

Karolina [17]

See the attached figure to better understand the problem

we know that
PB+BQ=1000 ft------->PB=1000-BQ-------> equation 1

in the triangle PAB
tan 50=AB/PB----------> AB=PB*tan 50------> equation 2

in the triangle ABQ
tan 25=AB/BQ------> AB=BQ*tan 25-------> equation 3

equals equation 2 and equation 3
PB*tan 50=BQ*tan 25--------> equation 4

substitute equation 1 in equation 4

[1000-BQ]*tan 50=BQ*tan 25-----> 1000*tan 50-BQ*tan 50=BQ*tan 25
BQ*[tan 25+tan 50]=1000*tan 50-----> BQ=1000*tan 50/[tan 25+tan 50]
BQ=718.76 ft
PB=1000-718.76-----> PB=281.24 ft
AB=PB*tan 50-----> 281.24*tan 50------> 335.17 ft

the answer is
335.17 ft
