Prove that the points (0, 0, 0),(1, 1, 0),(1, 0, 1) and (0, 1, 1) are the vertices of a regular tetrahedron by showing that each of the six edges has length √
2.
(b) Use the dot product (or cross product) to find the angle between any two adjacent edges of
the tetrahedron

A dot product is the product of the magnitude of the vectors and the cos of the angle between them. A cross product is the product of the magnitude of the vectors and the sine of the angle that they subtend on each other.

Step-by-step explanation:

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

the answer is 11.2 (i know i’m late)
