Question

Sec20°/csc70°
Do it fassssst plz help

Answer 1

Answer:

sec20° ÷ cosec70° = 1

Step-by-step explanation:

As the name suggests 'csc' or 'cosec' or 'cosecant' is the complementary angle of secant.

So, when sec θ is given as 20°, we know that its compliment would be:

90° - 70° = 20°

This means that sec θ = cosec (90° - θ)

According to the given Question,

   sec 20° = cosec (90° - 20°)

⇒ sec 20° = cosec 70°

Dividing by cosec 70° on both sides,

→ sec 20° ÷ cosec 70° = cosec 70° ÷ cosec 70°

→ sec 20° ÷ cosec 70° = 1
