When you have manipulated a matrix so that you can read the solution from it, you have to put it in reduced form. true or false

True

Step-by-step explanation:

We are given the statement,

'A matrix manipulated so that we can read the solution from it, is a matrix in the reduced form'.

This statement is true.

As, in order to find a solution of a system of equations, we cannot find the solution directly.

We have to apply various types of transformations in order to obtain the 'Reduced-Echelon form', which provides the solution.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
