Question

if tanx=coty=a,then (x+y)=?​

Answer 1

Ur Answer Is : x+y =90

Step-by-step explanation:

If tanx=coty

No need of a

Now, tanx=tan(90-y)

On compairing both the sides...

We get,

x=90-y

Then,

x+y=90

Answer 2

tanx=1/tany

tanx.tany=1

we know that

tan(x+y)=(tax+tany)/1-tanx.tany

tan(x+y)=tanx+tany/(1-1)=1/0=infinity

tan(x+y)=infinty

x+y=90
