Question

find the value of a If cot A if cot A = √3​

Answer 1

Answer:

The value of A is 30°.

Step-by-step explanation:

Given that:

cot A = √3

To Find:

The value of cot A.

Finding the value of cot A:

According to the question.

⟶ cot A = √3

⟶ cot A = cot 30°

Cancelling cot both sides.

⟶ A = 30°

∴ The value of A = 30°

Some useful trigonometric ratios:

• sin 0° = 0
• sin 30° = 1/2
• sin 45° = 1/√2
• sin 60° = √3/2
• sin 90° = 1

• cos 0° = 1
• cos 30° = √3/2
• cos 45° = 1/√2
• cos 60° = 1/2
• cos 90° = 0

• tan 0° = 0
• tan 30° = 1/√3
• tan 45° = 1
• tan 60° = √3
• tan 90° = undefined

Answer 2

Given,

• cotA = √3

To Find,

• The Value Of A.

Solution,

cotA = √3

We Know That,

√3 = cot30° •••(1)

→ cotA = √3

→ cotA = cot30°

So,

A = 30°

Required Answer,

If,

cotA = √3

Then,

A = 30°
