Answer:

CotA=√15/7

Explanation:

cosecA=8/7=hypotenuse/perpendicular

We have to find cotA

We do this by right angled triangle

We use pythagoras theorem to find the base

Base²+Perpendicular²=hypotenuse²

Base²+7²=8²

Base²=15

Base=√15

cotA=Base/Perpendicular

= √15/7

Answer:
Cot\theta =(√(15) )/(7)

Explanation:

Since, given
cosec\theta=(8 )/(7)

And we know that
Cot\theta=√(cosec^2\theta-1)

Therefore,
Cot\theta=√(cosec^2\theta-1) = √((8/7)^2-1)= √(64/49-1)


Cot\theta=√(64-49/49)=√(15/49)=√(15)/7

Thus,
Cot\theta =(√(15) )/(7)
