MCQ
The two angles of a triangle are complementary. The third angle is:
  • A
    $60^\circ$
  • B
    $45^\circ$
  • C
    $36^\circ$
  • ✓
    $90^\circ $
✓

Answer

Correct option: D.
$90^\circ $
$\therefore$ A triangle has $180^\circ$ and if two angles are complementary i.e. sum of two angles is $90^\circ ,$ then third angle will be $180^\circ - 90^\circ = 90^\circ .$
