Step-by-step explanation:
Consider the ladder wall system as a right angled triangle such that length of the ladder be the hypotenuse, length of wall till the ladder be perpendicular and distance between the foot be the base
Thus, H2=P2+a2
152=122+a2
225=144+a2
a2=81
a=9 cm
Thus, distance between the foot of the ladder and the wall is 9 cm.
Step-by-step explanation:
Given: ladder = 17 m and base = 8 m
The ladder forms a right triangle with the base of 8 m, the wall will be 15 m and the ladder (hypotenuse) is 17 m.
Let’s say you did not know that this was a standard 8–15–17 right triangle.
This is how you can figure it out:
hypotenuse(h)² = side ²/1 + side²/2
Let side 1 = base and side2 = wall
17² = 8² + wall²
wall = √17²−8²
wall = √289−64
wall = √225
wall = 15 feet
>>>>>>>>>>15 feet
is ur answer I hope it helps ☺️
