Question

If tan A = 3/4 and A + B = 90°, then what is the value of cot B ?

Answer 1

Answer:

tanA=cot(90-A)=cotB=3/4

Answer 2

Cot B = 3/4

Step-by-step explanation:

Given: tan A = 3/4 and A + B = 90°

Find: value of Cot B

Solution:

 B = 90°- A

tan A = 3/4

tan A = Cot (90-A)

Tan A = Cot B

Therefore Cot B = 3/4
