In str, h is the centroid, eh = 6,dh = 4, and sm = 24.
find each measure.
7.sh
8.hm
9.th
10.hr
11.td
12.er

  7. 16

  8. 8

  9. 8

  10. 12

  11. 12

  12. 18

Step-by-step explanation:

The centroid cuts each median into parts in the ratio 2:1. This fact can be used to find the desired lengths.

7. SH = 2/3×SM = 2/3×24 = 16

8. HM = 1/3×SM = 1/3×24 = 8

9. TH = 2×DH = 2×4 = 8

10. HR = 2×EH = 2×6 = 12

11. TD = TH +DH = 8 +4 = 12

12. ER = EH +HR = 6 +12 = 18

after simplifying it i got: -36.25 as my answer. hope that !

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
