What is the first step in the construction of a line perpendicular to and passing through an external point M? Assume that the construction uses only a compass and a straightedge. A.Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect .B. Place the compass needle at any point on , and set the compass width to M. C.Draw a line from point M passing through , and mark the point of intersection. D.Place the compass needle at any two points on , and draw two arcs through M.

step-by-step explanation:

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
