Answer: The flagpole is <u>
16 feet tall</u></h3>
==========================================================
Explanation:
The small markings for the angles in the diagram help us see how the angles pair up and how those pairs are congruent.
The square angle markers indicate we have 90 degree angles (aka right angles). That's one pair of congruent angles.
The other pair are the angles marked with small curves. We don't need to worry about the angle measure of these. All we care about is we have a second congruent pair of angles.
Having 2 sets of congruent angles allows us to use the AA (angle angle) similarity theorem.
The similar triangles allow us to set up the proportion below and isolate x.
-------------------
Let's solve for x.
6/x = 4.5/12
6*12 = x*4.5
72 = 4.5x
4.5x = 72
x = 72/(4.5)
x = 16
The flagpole is 16 feet tall.
This is somewhere between a 1 and 2 story building in terms of height.
Answer:A
Step-by-step explanation:
it is equivalent to 180-128 because its the same as the angle under route 2
and above runway 2
