70 points plus brainliest a 30 ft ladder leans against a building so that the top of the ladder touches the building at a point 17 ft above the ground. to the nearest tenth of a foot, how far from the bottom of the building is the bottom of the ladder?

a = 24.7 ft

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem.

a^2 + b^2 = c^2 where a and b are the lengths and c is the hypotenuse

a = the unknown distance fro the building and b is the distance up the wall, and the hypotenuse is the length of the ladder

a^2 + 17^2 = 30^2

a^2 +289 = 900

Subtract 289 from each side

a^2 +289-289 = 900-289

a^2 =611

Take the square root of each side

sqrt(a^2) = sqrt(611)

a = 24.71841419

To the nearest tenth

a = 24.7 ft
