A boat sails directly toward a 150-meter tall skyscraper that stands on the edge of a harbor. Let xx be the horizontal distance between the base of the building and the boat. The angle θ, measured in radians, is the angle of elevation from the boat to the top of the building. If the angle of elevation is π4\frac{\pi}{4} or 45∘45^{\circ}, how far from the building is the boat? (Note: It might be helpful to sketch a picture of the situation to determine an equation for this situation.) The boat is [Fill in the blank], meters from the building when the angle of elevation is π4\frac{\pi}{4} or 45∘45^{\circ}. Multiple fill-in-the-blank
