The arms of a double ladder are \( 150\,\mathrm{cm} \) long. After opening the ladder (look at the picture) the arms contain an angle of \( 40^{\circ} \). Calculate the height of the opened ladder (the distance between the highest point of the ladder and the ground). Round the result to the nearest integer.
\( 141\,\mathrm{cm} \)
\( 115\,\mathrm{cm} \)
\( 51\,\mathrm{cm} \)
\( 96\,\mathrm{cm} \)
