MCQ
$\angle\text{x}$ and $\angle\text{y}$ are exterior angles of a triangle $ABC$ at the points $B$ and $C$ respectively, Also, $\angle\text{B} >\angle\text{C},$ then the relation between $\angle\text{x}$ and $\angle\text{y}$ is:
  • A
    $\angle\text{x}$
  • B
    $\text{None of these}$
  • C
    $\angle\text{y}$
  • ✓
    $\angle\text{x} >\angle\text{y},$
✓

Answer

Correct option: D.
$\angle\text{x} >\angle\text{y},$
Since interior $\angle\text{B} >\angle\text{C},$
Hence $x < y.$
