Answer:
16.3
Step-by-step explanation:
You simply divide the 35.86 by 2.2 using long division or any method you'd like!
7.6x = 64
7.6/7.6
Therfore, x = 64/7.16
x = 8.938
6 miles is the entire diameter, divide that by 2 to get your RADIUS.
If the 3 points are collinear, then the slopes of all line segments connecting the points are the same.
Thus,
-6 - (-8) 2
m = ------------- = -------- = -1/2
-7 - (-3) -4
Then the following must be true:
4-(-6) 10
-1/2 = ------------ = ---------
c - (-7) c + 7
Cross multiplying, -(c+7) = 20, and c+7 = -20, so that c = -27
Answer:
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
