Question

if A+B=90°,cot B=3/4then tan A is equal to​

Answer 1

Step-by-step explanation:

A+B =90°

⇒A= 90°-B tanA = 3/4

⇒tan(90°-B) = 3/4

∵ tan(90°-A) = cotA

∴ tan(90°-B) = 3/4

⇒cotB = 3/4

$➾ ᴄᴏᴛ \: ʙ = ¾ - - - ⓐ$

$\: a \: + \: b \: = \: 90 \: \: ( given)$

$➾ ᴀ = 90° - ʙ$

$</p><p>➾ ᴛᴀɴ ᴀ = ᴛᴀɴ ( 90° - ʙ)$

$➾ ᴛᴀɴ ᴀ = ᴄᴏᴛ \: ʙ$

$➾ ᴛᴀɴ \: ᴀ = ¾ {from(1)}$

$therefore...$

$➾ ᴛᴀɴ \: \: ᴀ = ¾$
