Hey mates!!!

If
$\theta$
and
$2 \theta - 45$
are acute angles such that
$\sin( \theta ) = \cos(2 \theta - 45 )$
then what is the value of
$\tan( \theta)$

Please explain!!

Answer:

answer is 1

Step-by-step explanation:

as sintheta equals costheta theta has to be 45

MeSrijal: so basically......you have equated both given angles to find the value of theta

MeSrijal: right?

MathManiac: yeah...

MeSrijal: so 90 - theta is a compliment of theta

MathManiac: yes...but basic concept i uses is sin(theta)=cos(90-theta)

MeSrijal: 2theta - 45 is a compliment of theta?

MathManiac: has to be because only then would the condition guven in question will be true

MeSrijal: ok

MeSrijal: thanks for clearing my doubts

MathManiac: welcome
