If cot thita =rut2 then find sin thita

Answer»

ANSWER:

Sin∅ = 1/√3.

Step-by-step explanation:

Given,

cot∅ = √2

let,

cot∅ = adjacent side / opposite side = √2/1

Now,

According to PHYTHAGAROUS THEROM,

(AC)² = AB² + BC²

(AC)² = (√2)² + (1)²

(AC)² = 2 + 1

(AC)² = 3

AC = √3

:. AC = √3 units.

Now,

sin∅ = opposite side / adjacent side = BC/AC = 1/√3
