Question

IS THERE ANYONE WHO CAN HELP ME WITH MY MATH PLEASE?!?!?!

in triangle PQR, C is the centroid.


A. If CY = 10, find PC and PY

B. If QC = 10, find ZC and ZQ

C. If PX = 20 find PQ

Answer 1

The centroid divides each median in a ratio of 2:1

A. If CY = 10, find PC and PY
PC = 2(10) = 20
PY = 10 + 20 = 30

B. If QC = 10, find ZC and ZQ
ZC = 10/2 = 5
ZQ = 10 + 5 = 15

C. If PX = 20 find PQ
PQ = 2(20) = 40
