A ladder is set up against a building, as shown in the picture. How far up does the ladder reach on the building?

Round your answer to the nearest hundredth.

6.67 m

Step-by-step explanation:

It’s a ratio.

1.5/2=5/n

1.5n=2x5

1.5n=10

n=10/1.5

n=6.6666

n=6.67m

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
