Question

if angle a=30 and b=60 then find sin(a+b), cos(b-a), cosec(a+b)​

Answer 1

Answer:

sin 90+cos 60 × cosec 90 is the correct answer

Answer 2

$\huge\red{❥︎}\mathfrak\red{ANSWER}$

Given:- A =30 and B=60

Find:- Sin(a+b), cos(b-a), cosec(a+b)

Solution:-

➪ sin(a+b)

sin(30+60)

sin(90) = 1 answer...

➪ cos(b-a)

cos(60-30)

cos(30) = √3/2 answer...

➪ cosec(a+b)

cosec(30+60)

cosec(90) = 1 answer...
