Answer 1

Answer:

hope it's helpful for you

have a nice day please folloow me

Step-by-step explanation:

cosec = hypotenuse / opposite side

cosec = 1/ 1/2 = 2

cosec^2 = 2^2 = 4

cot = adjacent side/ opposite side

cot =(root 3/2) / (1/2)

cot = root 3

cot2 = 3

therefore, cosec^2 30°- cot^2 30º = 4-3 = 1
