Answer:
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
Answer:
A) n^15
B) 8z^12
C)(y^3)/(z^6)
Step-by-step explanation:
For a), it's basically n*n*n*... * n 8 times multiplied by n*n*n* .. *n 7 times, which is n multiplied by itself 15 times. So the answer is n^15
For b), you simplify 2z^4 to 2*z^4. Now, it is 2^3*z^4^3, and when you exponent an exponent, you multiply, so it is 8*z^12
For c) y^5/y^2 = y^3, and z^-2/z^4 = 1/z^6. Multiply them together to get y^3/z^6
