Question

The base of a 24 foot ladder is placed 8 feet from a wall. To the nearest tenth of a foot, how far up the wall does the ladder reach?

Answer 1

Answer:

a^2+b^2=c^2

Step-by-step explanation:

8^2+b^2=24^2

64+b^2=144

subtract 64 from both sides

b^2=80 take the square root of 80

b=8.9

the ladder is 8.9 feet up the wall
