Question

if cotA=8/15 find the value of cosecA and secA​

Answer 1

Answer:

cosecA = Hyp/Opp = 17/15

secA = Hyp/Adj = 17/8

Step-by-step explanation:

cotA = 8/15

cot = Adj./Opp.

Then Hypotenuse = √8² + 15²

= √64 + 225

= √289 = 17 cm

cosecA = Hyp/Opp = 17/15

secA = Hyp/Adj = 17/8

Answer 2

Answer:

if cot A = 8/15

cosA/sinA=8/15 = k (let)

so cos A =8k. and sinA = 15k

Now,

cosecA = 1 /sinA =1/15k

secA = 1/ cosA = 1/ 8k
