Given : AB || CD.
If $$\angle\, 4$$ is an obtuse angle, then $$\angle\, 5$$ is


ANSWER

Obtuse


SOLUTION
As $$AB||CD$$ and $$EF$$ is transversal.
$$\angle 5=\angle 4$$  (Alternate angles)
Now $$\angle 4$$ is obtuse therefore $$\angle 5$$ is also obtuse

If two line $$L_1$$ and $$L_2$$ in space,are defined by
$$\begin{array}{l}{L_1} = \left\{ {x = \sqrt \lambda  y + \left( {\sqrt \lambda   - 1} \right),z = \left( {\sqrt \lambda   - 1} \right)y + \sqrt \lambda  } \right\}and\\{L_2} = \left\{ {x = \sqrt \mu  y + \left( {1 - \sqrt \mu  } \right),z = \left( {1 - \sqrt \mu  } \right)y + \sqrt \mu  } \right\}\end{array}$$,
then $$L_1$$ is perpendicular to $$L_2$$ for all non-negative reals $$\lambda $$ and $$\mu $$, such that:

  • A. $$\lambda = \mu $$
  • B. $$\lambda \ne \mu $$
  • C. $$\lambda + \mu = 0$$
  • D. $$\sqrt \lambda + \sqrt \mu = 0$$
