these 2 triangles are proportional. we can use either of the sides to find x. im using the \(14.5\) one, as it seems easier \[\frac{10}{7} \cdot \frac{14.5}{x}\] cross multiply \[ 10 \times x =7 \times14.5 \] \[ x= \frac{7 \times14.5}{10} \] \[ x= \frac{101.5}{10} \] \[ \Large \color{Lightskyblue}{x}=?? \]
