27:31 can we solve for x using the four-sided shape ABCE? angle BCE has to be 90 degrees, as EC is perpendicular to BD. The 4 angles of a 4-sided shape add up to make 360 degrees, which we can then solve for x like this: x+52+66+90 = 360 x+208=360 x+208-208 = 360-208 x = 152?
多謝啊 sir, 咁有耐心教我們☺️☺️
唔好客氣 😊
好多謝你🤩好有用呀請你繼續教😭😭
可林Kelin[カリン] 多謝晒，請繼續支持😊

x = 152?
Yes, you can if you know the formula of Sum of interior angles of an n’th sided polygon is 180 degrees time (n-2) . Good thinking 👍

IQ question: the sequence stands for One Two Three Four Five etcetera, which means that the 8th one, or Eight, is an E.
Wow, you are the master in answering IQ questions 👍
CBA 可以嗎
魏雪 可以
抱佛腳 以為會教到好廢 點知抱到耶穌 完全配合我英文班超爛嘅我
Yulg_05 多謝支持😊，之後如果有咩問題唔識可以喺留言區發問
可不可以答下我
Liping Chen 是否關於條IQ題呢？若對條IQ題仍有疑問，我遲啲有機會再解釋多啲俾你聽
@@user-freetutorial 謝謝
個IQ題我依然不會
魔術牌這個題目
可以睇多一次，睇吓會唔會明白啲 😊
若果都係唔明白，我遲啲拍條片再解釋清楚啲
