Question

If cosθ =4/5, then the value of cosecθ/(1+cosθ) is :-

(a) 7/5 (b) 2/7 (c) 5/7 (d) 4/7​

Answer 1

Step-by-step explanation:

your answer is5÷3+9÷5=25+27÷15=52÷15

cos tita=4/5 at 37°

Answer 2

${\bf{\red{Given, cosθ=4/5}}}$

Therefore, sinθ = 3/5.

Now, cosecθ/(1+cosθ) = 5/3 /(1+ 4/5) = 5/3 × 5/9 = 25/27
