Question

Evaluate
Cosec 30°+Cosec 60°+Cosec 90°/sec 0°+sec 30°+sec 60°​

Answer 1

$\huge\rm\underline\purple{Question :-}$

Evaluate

Cosec 30°+Cosec 60°+Cosec 90°/sec 0°+sec 30°+sec 60°

$\huge\rm\underline\purple{Solution :-}$

$\green{\underline\bold{We\: know,}}$

Cosec 30° = 2

Cosec 60° = $\frac{2}{\sqrt3}$

Cosec 90° = 1

sec 0° = 1

sec 30° = $\frac{2}{\sqrt3}$

sec 60° = 2

$\red{\underline\bold{Putting\: the\:values\:we\:get,}}$

$\frac {Cosec 30°+Cosec 60°+Cosec 90°}{sec 0°+sec 30°+ sec 60°}$

= $\frac {2+\frac{2}{3}\sqrt3+1}{1+\frac{2}{3}\sqrt3+2}$

= $\frac {3+\frac{2}{3}\sqrt3}{3+\frac{2}{3}\sqrt3}$

= 1

$\pink{\underline\bold{ ∴ \:The\:required\:answer\:is\:1.}}$
