Question

In the given figure, AB$||$CD and BC$||$DE, then the value of x is _____________.

• A. ${95}^o$
• B. ${90}^o$
• C. ${85}^o$
• D. ${80}^o$

Answer 1

Answer: (A)

${95}^o$

$\angle ABC=\angle BCD={85}^{\circ }(\because AB||CD)$

And $\angle EDC=180-\angle BCD(\because BC||DE)$

$\Rightarrow x=180-85={95}^{\circ }$
