How tall would the lighthouse be?...

Mathematics
1 answer:
UkoKoshka [18]3 years ago
8 0

Answer:

122.6 m

Step-by-step explanation:

Shadow cast by the man = 3.1 m

Height of the man = 1.9 m

Shadow cast by the lighthouse = 200 m

Height of the lighthouse = x

If two shapes are similar, the ratio of their corresponding sides would be equal.

Therefore,

x/1.9 = 200/3.1

Multiply both sides by 1.9

x = (200*1.9)/3.1

x = 122.6 m (nearest tenth)

The lighthouse is 122.6 m tall

Answer:

  a=\sqrt{33}

Step-by-step explanation:

The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.

  a² = 7² -4²

  a² = 49 -16 = 33

  a = √33

Math help please help me with this page
White raven [17]
Please, post just one problem at a time, or (if you post more than one), indicate which one you want to focus on first.  Even more important, please do whatever you can to get started on each problem; I'm sure you know at least some basics.

What does "intersecting" mean?  Look it up if you're not sure.

Then what would "two intersecting lines" look like?  Draw the graph, or at least explain in words what the graph would look like.
