Question

If cosec (A+B)equal to 1 and cot (A-B) equal to root 3,0 degrees less than a+b less than or equal to 90 degrees ,a greater b,then find a and b​

Answer 1

Step-by-step explanation:

cosec(a+b)=(cosecA.cosecB)/(cotA+cotB)=1

cot(a-b) =(cotA.cotB-1)/(cota+cotb)=√3

cosec(a+b)=1=cosec(90)

a+b=90--(1)

cot(a-b)=√3=cot30

a-b=30----(2)

by elimination method

a+b-90-a+b+30=0

=>2b=60

=>b=30 substitute in (1)

a+30=90

=>a=60
