Answer 2

Answer:

Step-by-step explanation:

Formulas to remember -:

Sin (90-x) = cos x

cos (90-x) = sin x

Sec(90-x) = cosecx

cosec(90-x) = secx

Tan(90-x) = cotx

cot(90-x) =tanx

1. sin 70° = sin (90-20) = cos 20°
2. Sin 35° = sin(90-55) = cos 55°
3. cos 48° = cos(90-42) = sin 42°
4. cos 70° = cos(90-20) = sin 20°
5. cos 50° = cos(90-40) = sin 40°
6. sec 32° = sec(90-58) = cosec 58°
