Answer 1

Step-by-step explanation:

assume a right angled triangle with one of the angle 'theta' and solve for the sides using sin and hence find cot

Answer 2

Answer:

Step-by-step explanation:

sin β = 1/3 ⇒ sin²β = 1/9 ⇒ cos² β = 1 - 1/9 = 8/9

cot β = (cos β)/(sin β) ⇒ cot²β = (cos²β)/(sin²β) = 8/9 ÷ 1/9 = 8

2cot²β + 2 = 2×8 + 2 = 18
