Hey students! Try out this question.

It’s taken from an International School Year 11 IGCSE Additional Mathematics test. My student blanked out when he came to this question.. Duh. Then he blamed it on lack of sleep. What nonsense! (Owen, if you’re reading this you know I’m talking about you.)

Actually Owen has not turned 15 yet, and he’s doing Add Math. So, let’s cut him some slack ya.

Sorry, I forgot to show that the triangle is a Right Angled Triangle. It is Right Angled Triangle.. And with this you should know how to answer the question.

PS – I will post step by step solutions in a few days. Stay tuned.
