le that the shadow makes with the line joining the top of the building to the end of the shadow measures 45 degrees. What is the height of the building?
So first you want to draw out you triangle and label everything so side a would be x, side b would be 15 and c would be x next the angles need to be label and finally the anwser is 150m
