MCQ
If two complementary angles are in the ratio $3 : 5,$ then the angles are ________.
  • A
    $65^\circ , 35^\circ$
  • $65^\circ , 25^\circ$
  • C
    $15^\circ , 65^\circ$
  • D
    $15^\circ , 85^\circ$

Answer

Correct option: B.
$65^\circ , 25^\circ$

 Given that the ratio of two complementary angles is $13 : 5.$
Let the angles are $13x$ and $5x$ We know, $13x + 5x = 90^\circ $
$\Rightarrow x = 5$
Therefore, the angles are $65^\circ $ and $25^\circ .$
