Z is the centroid of A MVI. if MZ= 30, find ZR

ZR = 15

Step-by-step explanation:

Centroid of a triangle is a point inside the triangle where all medians meet.

And centroid divides the medians in the ratio of 2:1

By this property,

ZM : ZR = 2 : 1

ZM = 30 [Given]

Let the measure of median MR = a units

Therefore, ZM =

30 =

a = 45 units

Now, ZR =

ZR =

ZR = 15

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
