Problem 1 of 12.
This clip shows the solution to problem 1:
If a 650 cm ladder is placed against a building at a certain angle, it just reaches a point on the building that is 520 cm above the ground. if the ladder is moved to reach a point 80 cm higher up, how much closer will the foot of the ladder be to the building?
For best results, you should try this on your own before viewing the clip.
You can pause it at any point, if you feel you have sufficient information to continue on your own. Look at the solution only after having done this on your own.
