see 45°=?​

Answer 1

Answer:

undefined is the answer

As tan90°=undefined .So,if we add any thing to it also comes as undefined.....

If my answer is correct mark me as Brainliest......

Answer 2

tan90 + sec45

=tan 90 + 1/cos45

=infinity+√2

= R + {√2} = R

edit: one star seriously?

listen kiddo and all those people who think other answer is correct

than 90=sin90/cos90=1/0

dividing by zero doesn't makes it undefined its value in tend to any no. from +infinity to -infinity

for easy explanation of kids its given undefined but according to 12th maths tan90 is infinity

it mean all no. which indirectly is R

where R is all real no.

anything added to R is R only as it gets submerged in it in another words intersection.

"anything added with undefined is undifined" who taught you this??
