#9. A 4 mathrm{~m} ladder leans against a building. If the bottom of the ladder is 1.3 mathrm{~m} from the bottom of the building, how far up the wall will the ladder reach? Round your answer to one decimal place.

Question

Accepted Answer

Step:1 ：Use the Pythagorean theorem: (4^2 = 1.3^2 + x^2)Step:2 ：Solve for x: (x = sqrt{4^2 - 1.3^2} = 3.8)Step:3 ：(boxed{3.8}) meters up the wall
