Question

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

Answer 1

Hi ,

It is given that ,

tan A = 3/4 ---( 1 )

And

A + B = 90°

B = 90° - A

cot B = cot ( 90° - A )

Cot B = tan A

= 3/4 [ from ( 1 ) ]

Therefore ,

Cot B = 3/4

I hope this helps you.

Answer 2

Answer:

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

Cot B=3/4
