Which diagram best represents the problem

Multiple Choice

You need a ladder that will reach up a 25 foot tall house when placed 10 feet away from the house. How tall does the ladder need to be?

Which equation could be used to solve the problem?

• $$25^2\ +\ 10^2\ =\ c^2$$  

• $$25^2\ +\ b^2\ =\ 10^2$$  

• $$a^2\ +\ 10^2\ =\ 25^2$$  

• $$10^2\ +\ b^2\ =\ 25^2$$  

Pay attention as you work through the problems with the teacher.
