Question

Each letter is three. 5 m away from the base of the building. How high is window A?

Answer 1

Solution

A

Using pythagorean theorem

$\begin{gathered} 5.5^2=3.5^2+A^2 \\ 30.25=12.25+A^2 \\ Re-arrange \\ A^2=30.25-12.25 \\ A^2=18 \\ Take\text{ the square root of both sides} \\ A=\sqrt{18} \\ A=4.2426 \end{gathered}$

The final answer

The height of window A is

$4.24meters$
