Question

if 15 cot a = 28 then find value of cosec a​

Answer 1

Answer:

Step-by-step explanation:

15 cot a = 28

So,cota= 28/15 ---------------->1

We know that cot a= cosa/sina--------->2

Applying eqn. 2 in 1

Cosa/ Sina=28/15

Therefore, cosa=28 and Sina= 15--->3

We know that

Coseca= 1/Sina

From 3 ,

Coseca = 1/15

Answer 2

check your answer that is 10√10/15
