"I'm getting bored… bruh!" I again said and this time I annoyed her.
"Then do something… study… come on… solve this." She glared at me and pointed at a numerical in her mathematics book.
I leaned a bit closer and looked at the question. I remember seeing the figure and some of the values back when our teacher was solving this on the board. If my memory serves me right then I knew the correct answer.
"That's… x equals tan 30°." I said.
"How?... How !?" She was shocked out of her wits because it was quite a lengthy numerical and solving it mentally seemed out of the question for us. We were neither Ramanujan nor Aryabhatta.
"I remember seeing that once in the class." I said honestly.
"And you remember that?" She looked at me in disbelief.
"Sort of." Knowing my photographic memory, I nodded.
