Question

if cosA = 1/2 and sin B = 1/2 find the value of cosec(a+b)​

Answer 1

Answer:

answer will be 1 because only sin 30 and cos 60 are equal in value so

cosec 90 = 1

pls follow me

Answer 2

Answer:

cos A=1/2

A=60⁰

Sin B=1/2

B=30⁰

cosec(A+B)=cosec(60+30)⁰=cosec90⁰= 1

so, 1 is the answer

Thank Uhhh!!! ;)
