If cot ( 90 – A ) = 1 then angle A = ?




drop some thnx..​

Answer 1

Answer:

45

Step-by-step explanation:

cot (90 - A) = tan A

Now,

tan A = 1

But, tan 45 = 1

So, by correlating the two equations, we get that A = 45.

Answer 2

Answer:

Answer is 45

Step-by-step explanation:

Let

cos(90-A)=tanA

Now,

tanA=1

But,tan45=1

so,by correlating the two equations we get that

A=45
