Question

a 15 foot ladder is leaning against a wall. the bottom of the ladder is 5 feet from the wall. to the nearest foot, how far up the wall does the ladder reach!! please help!! and show work

Answer 1

the formula for this would be the Pythagorean Theorem. This meaning a²+b²=c²
so a²+15²=25, 15²=225, so a²+225=25, move the 225 over and a²=250, square root of 250 is 15.8 rounded up to 16 feet so, so a=16. but idk that might not be right
