Exams are over. I bet you are pleased. Ok a lot of you struggled with this one but you just need to train you mind to see the catches. Let's have another good look at it.You are asked what is the size of angle ABC? Oh dear how are you going to work that out. I hope you all remember what is sum of all interior angles of a triangle. Interior meaning the inside angles. As you can see the only angle they show at A is an outside angle. That is no good. Ok but let's use this information that they have given you. You are missing two angles angle B and angle A.
How will you work out the missing angle at A? If you fathom it out come and whisper in my ear in class, because you are now on the right track to be able to work it out. The size of angle C is 25 degrees and remember they want to know what is the size of angle B? Good luck and give it a try. Use my clue dective.
