# A rock is thrown from the roof of a building, with an initial velocity of \( 10 \) \( \text{m/s} \) at an angle of \( 30^{\circ} \) above the horizontal. The rock is observed to strike the ground \( 43 \) \( \text{m} \) from the base of the building. What is the height of the building assuming no air resistance?
