Which shape could be thought of as being created by stacking congruent polygons
Colt1911 [192]

When they talk about congruent polygons, they meant geometric figures that are all equal in shape and size.

It's angled, and the side length is equal too.

When you piled equal polygons, you'll end up with what we call prisms. It's the 3D form of a polygon.

If you stack squares, you'll have a cube.

If you stack octagons, you'll have an octagon prism.

If tan∅ = √15÷10, find cot∅
Ghella [55]

Answer:

cot(∅) = \frac{10\sqrt{15} }{15}

Step-by-step explanation:

tan ∅ and cot ∅ are inverse functions

therefore the inverse of

tan ∅ = √15 / 10

is equal to

cot ∅ = 10 / √15

Rationalizing the denominator

\frac{10}{\sqrt{15} } * \frac{\sqrt{15} }{\sqrt{15} }

cot ∅ = \frac{10\sqrt{15} }{15}
