Question

If Cot(A+B) = 1 ,then A+B is ..

Answer 1

Answer:

A + B = 45°

Step-by-step explanation:

Given that,

cot(A+B) = 1

⇒cot(A + B) = cot 45°                (∵cot45°=1)

remove 'cot' on both sides

⇒A + B = 45°

∴A+B=45°

Answer 2

$\huge\fcolorbox{red}{orange}{cot(A+B)\:=\:1}$

we know that $\huge\mathfrak\blue{cot\:45°\:=\:1}$

cot (A + B) = 1

cot (A + B) = cot (45°)

on comparing we get

$\huge\sf\bold\pink{A\:+\:B\:=\:45°}$
