In the diagram a person who is 6 ft tall is standing on the ground 3 ft away from point P. A line segment drawn from the top corner of the building to point P creates two similar triangles. Which proportion can be used to find h, the height of the building in feet?

3h=186\frac{3}{h}=\frac{18}{6}

63=h18\frac{6}{3}=\frac{h}{18}

315=h6\frac{3}{15}=\frac{h}{6}

63=18h\frac{6}{3}=\frac{18}{h}
