The Pythagorean Theorem works for all RIGHT triangles.
Two triangles must be congruent by SSS when their all sides would be equal.
So, BC = DF
AC = DE
Then, AB = EF = 10
In short, Your Answer would be Option B
Hope this helps!
Answer:
Answer B: -30
Step-by-step explanation:
Let B be as follows:
[-18 3]
[4 1 ]
To find the determinant, multiply diagonally <em>downward</em> from -18 through 1, obtaining -18. We keep this sign as is.
Continue: Start at 4 and move diagonally <em>upward</em> through 3; this product is 12. Because we moved upward, give this result the opposite sign: -12.
Now add together these two products; that is, add together -18 and -12. Here the sum is -30. This is the determinant of the matrix. It's Answer B.
Finding the determinant of a 3x3 matrix obviously requires more steps, but the general approach is similar.
