Question

Cos63°sec(90°-THETHA)=1
find the value of thetha

Answer 1

Heya user !!!

Here's the answer you are looking for

$cos63sec(90 - \alpha ) = 1 \\ \\ we \: know \: that \: cos( \alpha ) \sec( \alpha ) = 1 \\ \\ so \: for \: cos63sec(90 - \alpha ) = 1 \: \\ \\ 63 \: must \: be \: equal \: to \: (90 - \alpha ) \\ 63 = 90 - \alpha \\ \alpha = 90 - 63 = 27$


Therefore, the value of the variable is 27.
