Question

if A+B=90°and tanA=3/4,the value of cot B​

Answer 1

Answer:

3/4

Step-by-step explanation:

A+B = 90°

A = 90 - B

TanA = Tan(90-B)

TanA = CotB

Thus CotB = 3/4.

Answer 2

Question :

If A + B = 90°and tanA = 3/4, the value of cot B.

Given :

tan A = $\frac{3}{4}$ ––――( 1 )

A + B = 90°

To Find :

• Value of cot B.

Solution :

B = 90° - A 

cot B = cot ( 90° - A )

Cot B = tan A

= $\frac{3}{4}$ [ from ( 1 ) ]

Therefore ,

Cot B = $\frac{3}{4}$
