Answer:
RX = 12 and XU = 6
Step-by-step explanation:
Given : In ΔTRV , TW ,RU and VS are the medians .
X is the centroid
To Find : RX and XU
Solution:
Since we know that the centroid divides each median in a ratio of 2:1.
Since X is the centroid so RX : XU = 2:1
So, let RX = 2x and XU = x
And we are given that RU = 18
⇒RX +XU=18
⇒2x+x=18
⇒3x=18
⇒
⇒
Thus, RX = 2x = 2*6 =12
XU = x =6
Hence length of RX = 12 and XU = 6

Answer:
144°
Step-by-step explanation:
First, find the area of the circle, with the formula A = r²
Plug in 10 as the radius, and solve
A = r²
A = (10²)
A = 100
Using this, create a proportion that relates the area of the sector to the degree measure of the arc.
Let x represent the degree measure of the arc of the sector:
=
Cross multiply and solve for x:
100x = 14400
x = 144
So, the degree measure of the sector arc is 144°
Area= 14.142
Perimeter=20
Height=3.14
