Question

This answer was confusing for sure

Answer 1

heyy matee

we got equation

( sin Θ ) ^ 2 + ( cos Θ ) ^2 = 1

now look at beauty of ques

Θ = 180

and u must be knowing sin 180 = 0 and cos 180 = -1

so

(0)^2 + (-1)^2 = 2

and done we are done with ques

ans is option d

u must be thinking why not other values are same but this is thing we got in option d it is exact equation we got so i can give 90% guarantee
