A 9 foot ladder is placed against a building. If the base of the ladder is 7 feet away from the building,
how far up the building will the ladder reach? Round the answer to the nearest tenth.
X =
Use Pythagorean Theorem a^2+b^2=c^2 The longest side being c because it’s thy hypotenuse and the other length being any one of the legs (either a or b).
7^2+b^2=9^2 —> 49+b^2=81 —> b^2=81-49 =32 Sqrt of 32 = b = 5.7
