Answer:
True
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
Answer:
x=21
Step-by-step explanation:
since the triangle is isosceles, the two lower angles are equal.
2(2x+3)=90
4x+6=90
4x=84
x=21
10 and 12 you never get the number that’s on the slanted side I learned this but I forgot if u add or multiply but the digits that should be used r 10 and 12
Answer:
132 degrees
Step-by-step explanation:
This is because if you have a 90 degree angle than the angles connected to it will be equal
