A vertical pole, 40 feet tall, casts a shadow onto the ground. If the angle of elevation from the tip of the shadow on the ground to the top of the pole is \( \theta=67^{\circ} \), use the dimensions given to find the length of the shadow, \( a \), in feet. Do not include the units in your answer. - Round the answer to the nearest tenth.
