Question

Express each of the following in terms of angles between 0° and 45°
.
please solve all three with steps and Don't give irrevelent answers​

Answer 1

(1) sin 59° + tan 63°

= sin(90-31) + tan(90-27)

=cos 31 + cot 27

(2) cosec 68° + cot 72°

= cosec(90-22) + cot(90-18)

= sec 22 + tan 18

(3) cos 74° + sec 67°

=cos(90-16) + sec(90-23)

=sin 16 + cosec 23

Answer 2

Answer:

1) sin 59⁰ + tan 63⁰

= sin (90-31) + tan (90-27)

= cos 31⁰ + cot 27⁰

2) cosec 68⁰ + cot 72⁰

=cosec (90-22) + cot (90-18)

= sec 22⁰ + tan 18⁰

3) cos 74⁰ + sec 67⁰

= cos (90-16) + sec (90-23)

= sin 16⁰ + cosec 23⁰
