10. How can you use similar triangles to solve real-world problems?

8090 [49]

Similar triangles can be extremely useful in architecture. For example, similar triangles can help represent doors and how far they swing. Also when using shadows that make the triangles you can use them to find the height of an actual object they can be used to construct many architectural designs and monuments for e.g, bridges. You can also determine values that you can’t directly measure. For e.g you. Can measure the length of your shadow and a tree’s shadow on a sunny day.

Step-by-step explanation:

<u>Step 1: Define</u>

$\displaystyle ln(x^2) = -2$

<u>Step 2: Solve for </u><em><u>x</u></em>

Raise both sides by e: $e^{\displaystyle ln(x^2)} = e^{-2}$
Simplify equation: $x^2 = e^{-2}$
Square root both sides: $x = \pm e^{-1}$
