$31$ meters

Work Step by Step

The trigonometric ratios are as follows: $\sin \theta= \dfrac{opposite}{hypotenuse}$ ; $\cos \theta= \dfrac{Adjacent}{hypotenuse}$ and $\tan \theta= \dfrac{Opposite}{Adjacent}$ Since, $\theta=32^{\circ}$ Then $\tan 32^{\circ}= \dfrac{a}{50}$ So, $ a =50 \times \tan 32^{\circ} =50 \times 0.625$ Our required answer is: $ a \approx 31$ m
