Answer:
82
Step-by-step explanation:
its vertical so, 32+32 = 64 and 360 - 64 = 328/2 = 164/2 82
Reasons why you use 360 is because the whole shape equals 360
the reason why i divided it 2 times is because there's 4 side angles each angle needs a number.
I may be wrong.

Answer:
b. BC
Step-by-step explanation:
The first thing is to calculate the dimensions of each matrix, that is, the number of rows x number of columns:
dimensions of A: 2x2
B dimensions: 2x3
C dimensions: 3x3
D dimensions: 1x3
We have that a matrix multiplication is defined, the internal numbers of its dimensions must be the same: we analyze each option:
BA: (2x3) * (2x2): the internal numbers do not match (a 3 for B and a 2 for A), so the multiplication of the matrix is not defined
BC: (2x3) * (3x3): the internal numbers are both 3, so the matrix multiplication is defined
CB: (3x3
) * (2x3): the internal numbers do not match (a 3 for C and a 2 for B), so the multiplication of the matrix is not defined
CD: (3x3) * (1x3): the internal numbers do not match (a 3 for C and a 1 for D) so the multiplication of the matrix is not defined
Therefore the answer is b. BC

Answer:
Sound can travel 12 miles per minute.
Step-by-step explanation:
Speed equation is distance divided by time.
So we have 1 mile per 1/12 of a minute.
Let’s write the equation.
Speed of sound = 1 / 1/12
Multiply by the reciprocal.
1 * 12 = 12.
