Matriculation level  #n+41. The angles of elevation and depression of the top and bottom of a lighthouse from the top of a building 60 meters high are 30° and 60° respectively. Character is who you are when no one is looking. #2 20090104 22:55:23
Re: Matriculation level  #n+4Are these questions also for teenagers? #3 20090105 23:19:17
Re: Matriculation level  #n+4Oh yes, the title says so! I don't know the UK equivalent of Matriculation ( I guess GCSE). Students aged 1416 normally appear for the examination. Character is who you are when no one is looking. #4 20090106 03:01:53
Re: Matriculation level  #n+4If this is equivalent to GCSE, the British education system is rubbish. Here, the trig questions wouldn't be encountered (usually) until AS/A level (1618). #5 20090106 22:59:57
Re: Matriculation level  #n+4I remember we were asked to make a clinometer (an inclinometer), a simple one, to measure the angle of elevation and hence find the height knowing the base distance. I guess I was 13 then. Soon, I shall post topics in Exercies which 1618 year olds are expected to know thoroughly to do fairly well in Mathematics! Character is who you are when no one is looking.
