Answer the first word problem ! and show work

b= 9.17 ft

Step-by-step explanation:

The 4 feet from the wall is the bottom part of the triangle. The 10 ft. ladder is the hypotenuse of the triangle. Use the Pythagorean Theorem and substitute the known values.

a^2+b^2=c^2

4^2+b^2=10^2

Then square all the known values

16+b^2=100

Then get b by itself

b^2=-16+100

add -16 and 100

b^2=84

and finally square root both sides of the equation

b=9.16515 ft or 9.17 ft

c
