Because this is a right triangle and it is given that one angle is 45 than also the ather angle is 45 so this triangle has 2 equal sides.So also the ather side is 6 .
Hypotenuse can be found by pythagorean theorem
6^2+6^2=x^2
36+36=x^2
x=√72
Answer:
-136
Step-by-step explanation:
We have to find the determinant of the following matrix:
We can find the determinant by expanding via 1st column. i.e. by taking each element of 1st column and multiplying it by its co-factor matrix as shown below:
det
=
The notation det() stands for determinant of the matrix.
Therefore, the determinant of the given matrix is -136
