We know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
V - E + F = 2
clear F
F=2-V+E
in this problem
V=8
E=14
F=?
so
F=2-8+14
F=8
the answer is8 faces
Answer:
there are 2100 seconds in 35 minutes
= 120/100 x 320
= 12 x 32
= 384
So there is a possibility I read it wrong, or you typed it wrong. but from what I see, there are NO right triangles.
Step-by-step explanation:
a right triangle has a 90 degree angle. none of these have one.
