Question

if cos 40 = sin 50 , (0<0< 90°), then the value of 0 is​

Answer 1

Answer:

sin(90-40)=sin50

sin(50)=sin50

=0

Answer 2

Answer:

it's theta ig

or if it's zero then it's a property

for theta

cos4theta =sin5theta

cos(90-theta) sin theta

cos 4theta =cos(90-5theta)

comparing angles we get

4theta=90-5theta

theta=10
