Question

If tan A = 3/4 and A + B = 90° then find cot B.

Answer 1

Step-by-step explanation:

A + B = 90

A = (90 - B)

tan (90 - B) = 3/4

And as you know that tan (90 - B) = cot B

cot B = 3/4

Hope it helps

Answer 2

Answer:

• Given :A+B =90°
• Tan A = 3/4
• A+B =90°
• B(90°-A)
• cotB =cot (90°-A)
• =Tan A

Ans =3/4
