Slide 12

Ladder Problem Solution

First draw a diagram that shows the sides of the right triangle.

Label the sides:

Ladder is 25 m

Distance from house is 7 m

Use a2 + b2 = c2 to solve for the missing side.

Distance from house: 7 meters

Slide 13

Ladder Problem Solution

72 + b2 = 252

49 + b2 = 625

b2 = 576

b = 24 m
