Answer:
Step-by-step explanation:
Notice that you are being asked to perform the product of a scalar (the number "-10" times a 2 by 2 matrix.
Such type of product requires the multiplication of each element of the matrix by the scalar "-10"
That means that the element 23 gets transformed into "-230"
The element -38 gets transformed into "380"
The element 17 gets transformed into "-170"
and lastly, the element -6 gets transformed into "60"
Such modification gets reflected in the second matrix listed among the possible answers.
We have been given a diagram. We are asked find the measure of arc EAB.
First of all, we will find the measure of arcs ED and CB using our given information.
We know that measure of an inscribed angle is half the measure of intercepted arc.
We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.
Similarly, we will find the measure of arc DCB.
Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.
