The ladder is leaning against the wall of a house. Its length is \( 5 \) meters. How high does the ladder reach if the angle between it and the wall is \( 45^{\circ} \)? (See the picture.)
\( \frac{5\sqrt2}{2}\,\mathrm{m} \)
\( \frac{5}{2}\,\mathrm{m} \)
\( \frac{5\sqrt3}{2}\,\mathrm{m} \)
\( \frac{10}{\sqrt2}\,\mathrm{m} \)
