Q. |
## A line of length 10 cm at first lied on the horizontal plane parallel to vertical plane and then keeping one of its ends fixed turned 30 degrees with respect to vertical plane and then turned 45 degrees with respect to horizontal plane. What is the length of line in front view? |

A. | 8.66 cm |

B. | 7.07 cm |

C. | 3.53 cm |

D. | 6.12 cm |

Answer» A. 8.66 cm | |

Explanation: first imagine the line in horizontal plane parallel to vertical plane as here we are asked to find the front view’s length even if the line is rotated with respect to horizontal plane the line length will not change and then rotated with respect to the vertical plane which is calculated as follows 10 x cos (30) =8.66 cm. |
