A 13-foot long ladder leans against the wall. the foot of the ladder is at a distance of 5 feet from the base of the wall.
1 answer:
Answer:
The distance, in feet, from the ground to the ladder is 12 feet.
Step-by-step explanation:
To answer this question, we must use the Pythagorean Theorem- a^2+b^2=c^2. C is the hypotenuse, and a and b are legs.
We have: 5^2+b^2=13^2
Simplifying: 25+b^2=169
Subtracting 25 from both sides: b^2=144
B=12.
