Question

find the value of theta where theta is smaller than 90 degree and greater than zero degree

Answer 1

hey food I think it will help you

Answer 2

1 ) cos 63° . Sec (90-theta) = 1
cos 63° . Sec (90-27) = 1
cos 63° . cosec 63° = 1
cos 63° . Sec (90-27)= 1
Cos 63° . Sec 63° =1
1 / Sec 63° . Sec 63° = 1 [Cos = 1 / sec]
1 = 1 Answer.
The value of theta is 27°.....
2 ) Tan 35° . Cot ( 90- 35 ) = 1
Tan 35 °. Cot ( 90 - 35 ) = 1
Tan 35° . Tan 55 ° = 1
Tan 35 ° . Tan ( 90-35) =1
Tan 35° . Cot 35° = 1
Tan 35 ° . 1 / Tan 35 ° = 1
1 = 1 answer..
The value of theta is 35°......
