If the angle of elevation of Sun increases from 0° to 90° then the length ofshadow of a tower decreases. Is this true ? Justify your answer. |

Answer» Let the height of tower is h unitsand length of shadow is d unitsinitially, angle of elevation is 0°tan0° = h/d = 0that means length of shadow is∞(infinity) = maximumfinally,tan90° = h/d =∞that means length of shadow is 0 =minimum∴as the angle of elevation increases from 0° to 90°, the length of shadow decreases from maximum to minimum. |
