The horizontal distance between the base of the ladder and the wall is: 11.8 foot
the possibilities are probably b, using the elimination method
So 55% is really 55/100
You take 100 - 55 to find how much Mr. Williams drove
100 - 55 = 45
So Mr. Williams drove 45/100 of the miles
Simplified is 9/20 of the miles
The triangles are similar because of the SAS postulate. The sides are proportional and angle T is equal in both.
