Question

If sin(alpha)=3/5
and cos(beta)=3/5
0 Then
A)Alpha=beta,
B)alpha C)alpha>beta

Answer 1

here your ans must be alpha=beta

take an example,ok

sin 30= 1/2

cos 60=1/2

similarly here alpha and beta have to be different but have the same value with sin and cos respectively.

Hence ans is (A)

Thank you.

Hope this helps you....

i have used the graph of sine and cosine functions to find the answer see the attachments for the answer
