Question

How to solve this problem

Answer 1

Check the picture below.

so let's use the pythagorean theorem

`\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ c^2=a^2+o^2 \end{array} \qquad \begin{cases} c=\stackrel{hypotenuse}{x}\\ a=\stackrel{adjacent}{11.3}\\ o=\stackrel{opposite}{8.8} \end{cases} \\\\\\ (x)^2= (11.3)^2 + (8.8)^2\implies x^2=205.13\implies x=√(205.15)\implies x\approx 14.3`
