Answer:
[tex]c\approx63\Rightarrow\text{ Option two}[/tex]
Explanation: The doc=to door distance can be calculated using the Pythagorean theorem, which states the following:
[tex]a^2+b^2=c^2\Rightarrow(1)[/tex]
According to the diagram, the known and the unknowns for equation (1) are as follows:
[tex]\begin{gathered} a=110m \\ b=90m \end{gathered}[/tex]
Plugging these values in equation (1) gives the following answer:
[tex](110)^2+(90)^2=c^2[/tex]
Solving for the c gives the answer, the steps are shown as follows:
[tex]\begin{gathered} c^2=(110)^2+(90)^2 \\ c=\sqrt{(110)^2+(90)^2} \\ c=\sqrt{12100-8100} \\ c=\sqrt{4000}=63.245 \\ c\approx63 \end{gathered}[/tex]
In conclusion, the answer is Option Second.
