Question

Sec5theath is equal to cosec theata minus 36 find theta

Answer 1

$<b > Answer :-$



_____________________________

Given :-

sec5∅ = cosec ( ∅ - 36° )

[ ∅ = theta ]

To find :-

The value of ∅

Salutation :-

sec5∅ = cosec ( ∅ - 36° )

sec5∅ = sec { 90° - ( ∅ - 36 ) }

[ • As we know , sec ( 90° - ∅ ) = cosec∅ ]

5∅ = 90° - ∅ + 36°

5∅ + ∅ = 126°

6∅ = 126°

∅ = 126° / 6

∅ = 21°

•°• The value of ∅ is 21°
