The Washington Monument, in Washington, D.C., is 555 feet 5% inches tall and weighs 90,854 tons. The monument is topped by a square aluminum pyramid. The sides of the pyramid's base measure 5.6 inches, and the pyramid is 8.9 inches tall. Estimate the slope that a face of the pyramid makes with its base. Round to the nearest tenth.

Respuesta :

Sides of the pyramid are:

5.6 inches base

Height of the pyramid is:

8.9 inches

Let's recall the formula of the slope:

Slope = Change in y/Change in x

Let x = 8.9 or change in vertical distance

Let y = 2.8 or change in horizontal distance

Slope = 8.9/2.8

Slope = 3.1785

Slope = 3.2 rounding to the next tenth
