A child of height 1.2 metres stands 3 metres from the foot of a lamp post of height 2.8 metres, at the top of which there is a small source which can be considered as a point. What is the length of the shadow cast by the child upon the ground?
We did the previous problem for you. It is very similar to this problem. Please try it. It is really just trig.
can someone help? i am really struggling
could i have a clue or a starting point please?
2.8/(3+x) = 1.2/x,
2.8• x =1.2•3+1.2•x,
