Question

tan 60 degree ×ton dash is equal to 1​

Answer 1

Answer:

30°

Step-by-step explanation:

Let the required angles be A.

⇒ tan60° tanA = 1

⇒ tan60° = 1/tanA

⇒ tan60° = cotA

Using tan(90 - θ) = cotθ

⇒ tan60° = tan(90 - A)

⇒ 60° = 90° - A

⇒ A = 90° - 60°

⇒ A  = 30°

Answer 2

• Let required angle = x

1. tan 60 degree tan x = 1
2. tan 60 Degree = 1 / tan x
3. tan60° = cot x

Use :-

tan (90 - theta) = cot theta

tan60 degree = tan(90 - x)

60 degree = 90 degree - x

x = 90 - 60

x = 30 degree

Answer = 30 degree
