Question

if tan9thetha equals to COT theta then find the value of theta​

Answer 1

Answer:

1/9 cot theta

Step-by-step explanation:

Answer 2

Step-by-step explanation:

let theta = α

given, tan9thetha equals to COT theta

=> tan 9α = cot α

=> tan 9α = tan (90°-α)

=> 90°-α = 9α

=> 9α + α = 90°

=> 10α = 90°

=> α = 9°

.•. value of theta = 9°
