Using a protractor will help but in general vertical angles on a straight line add up to 180 degrees.
If the product of two matrices is an identity matrix then, one matrix is inverse of the other. i.e. AB = I then, A = B-1 and B = A-1Inverse of matrix can be found by using these two results:A = AI and A = IA.By using these results inverse of a matrix can be found by applying same elementary row or column operation on both sides. A on R.H.S. remains as it is.

One way to solve this system of equations is by using matrices. Form an augmented matrix in which the first 2x2 matrix is the coefficient matrix and the 2x1 matrix on its right is the answer. Now apply Gaussian Elimination and back-substitution. Using this method gives x=5 and y=1.
You find the angle with a fixed direction using trigonometry. You then convert it to an angle measured in degrees, clockwise from North, and written as a three digit number.
For every point A = (x,y) in your figure, a 180 degree counterclockwise rotation about the origin will result in a point A' = (x', y') where: x' = x * cos(180) - y * sin(180) y' = x * sin(180) + y * cos(180) Happy-fun time fact: This is equivalent to using a rotation matrix from Linear Algebra! Because a rotation is an isometry, you only have to rotate each vertex of a polygon, and then connect the respective rotated vertices to get the rotated polygon. You can rotate a closed curve as well, but you must figure out a way to rotate the infinite number of points in the curve. We are able to do this with straight lines above due to the property of isometries, which preserves distances between points.
The Earth rotates 14.9590452 degrees per hour.

A Hadamard Matrix is a square matrix composed of 1 or -1. Using a square matrix system the hadamard matrix could be created
This represents the size of matrix inverted with each literation.
Memory allocation is not necessary to display a matrix.
Using a protractor will help but in general vertical angles on a straight line add up to 180 degrees.
It depends on how big and what materials you are using. A minimum of 5 degrees from center is usually considered safe from collapse if you are using strong roof planks/trusses.
