Aregular triangular pyramid has all of edges of length 36. what is the angle between any two faces of this pyramid?

The angle between any two faces of this pyramid is equal to

Step-by-step explanation:

we know that

An equilateral triangle has three equal sides and three equal internal angles of measure 60 degrees

In this problem

All the faces in the regular triangular pyramid are equilateral triangles.

therefore

The angle between any two faces of this pyramid is equal to

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
