If you draw this one, you would actually form a right triangle, where the hypotenuse is the length of the ladder (15 ft), and one of the legs is the distance from the wall to the bottom end of ladder (9 ft). What we're looking for is also the length of the other leg.
Recall the Pythagorean theorem:
c^2 = a^2 + b^2
where c is the hypotenuse and a & b are the legs. Substituting,
15^2 = 9^2 + b^2
225 - 81 = b^2
144 = b^2
b = 12 ft
Hope this helps :3
A15- foot ladder is leaning against a 30- foot wall. The bottom end of the ladder is 9 feet from the wall. How many feet above the ground does the ladder touch the wall.
Can someone please help me with this question

a^2+b^2=c^2 6 and 7 we are finding the hypotenuse so 6*6=36 7*7=49 49+36=85 and from their
right triangle:a^2+b^2=c^2 6 and 7 we are finding the hypotenuse so 6*6=36 7*7=49 49+36=85 and from their you square 85 = 9.22 HOPE THIS HELPED!!!!!!!!!!!!!!!!!!!!!!!!!!
