Apainter leans a 20-ft ladder against a building. the base of the ladder is 12 ft from the building. to the nearest foot, how high on the building does the ladder reach?

using Pythagorean Theorem

 you have 20^2 = 12^2 +X^2

400 = 144 +x^2

256 =x^2

x = sqrt(256)

x = 16

 the ladder reaches 16 feet up the building

i dont know it

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
