Question

Cot B=3/4 and A+B=90°,then find the value of tan A

Answer 1

Hey ^_^

A+B = 90°
A= 90°-B

tan A = tan (90-B) = cotB

Therefore ,
tanA = 3/4

☺

Answer 2

Hi...☺

Here is your answer...✌

================================
A+B = 90°

A = 90°-B ___(1)

Now,

TanA = Tan(90°-B) ___(from (1))

= CotB ___(since, Tan(90°-X) = CotX)

= 3/4
