Let's draw the diagram:
We need to find the horizontal distance. Let's call it "x".
We can use pythagorean theorem to solve this.
Pythagorean Theorem:
[tex]c^2=a^2+b^2[/tex]Using Pythagorean Theorem, you can write:
[tex]15^2=x^2+3^2[/tex]Solving:
[tex]\begin{gathered} 15^2=x^2+3^2 \\ 225=x^2+9 \\ x^2=225-9 \\ x^2=216 \\ x=\sqrt[]{216} \\ x=14.6969 \end{gathered}[/tex]We have to round to nearest 10th , that means 1 decimal place.
So, correct answer is:
14.7 feet
