This one is one with better lighting sorry about the last one, this is the backside. this is honestly confusing for me so pls help me this hw counts as an important grade
1. it says 1.8 for human and for humans shadow is 4.5 so what we should do is; 4.5-1.6= 2.7 so it says 8 meters for trees shadow so; 8.0-2.7= 5.3
sorry i dont have time to do all but for second question i think you should do; draw lines like it did for 3 and 4, and for the last one (the answer) is should be 7
