If an 8-foot ladder is leaned against a wall with its foot braced 4 feet from the wall's base, how far up the wall will the top of the ladder reach? round to the nearest hundredth.
we know that see the picture to better understand the problem in the right triangle ABC Applying the Pythagoras Theorem AB²=BC²+AC²-------> BC²=AB²-AC² AB=8 ft AC=4 ft BC²=8²-4²-----> BC²=48--------> BC=√48-------> BC=6.93 ft
