Answers

2. The bottom of a 13-foot straight ladder is set into the ground 5 feet away from a
wall. When the top of the ladder is leaned against the wall, what is the distance
above the ground it will reach?

Answers

Pythagorean theorem is: a^2+b^2=c^2

1.  10^2+b^2=17^2
     So 100+b^2=289
     b^2=189
     b=√(189)
     b=13 3/4
     The dimensions are 10 by 13 3/4
 
2.  5^2+b^2=13^2
     So 25+b^2=169
     b^2=144
     b=12
     The ladder reaches 12 feet off the ground
