Question

If x and y are complementary angles then prove that secx =cosec y

Answer 1

Step-by-step explanation:

x and y are complimentary angles

i.e. x +y = 90°

so, y = 90 - x ( 1 )

now, sec x = cosec ( 90 - x ) {complimentary

angles}

{ from equation ( 1 ) }

=>. sec x = cosec y ,. Hence proved.
