Answer:
1/2
Step-by-step explanation:
hello friend
given tan theta = 1
tan theta will be 1 if theta is 45
so value of theta is 45
now given
to find value of sin theta + cos theta/sec theta + cosec theta
cosec theta = 1 / sin theta
sec theta = 1/ cos theta
our equation becomes
sin theta + cos theta(sin theta . cos theta) / sin theta + cos theta
sin theta + cos theta gets canceled
so we are left with
sin theta . cos theta
sub value of theta in cos theta.sin theta
cos theta = 1/ Sq rt 2
sin theta = 1/ Sq rt 2
so we get sin theta . cos theta = 1/Sq rt 2.1/Sq rt 2
= 1/2
hope it helps you
