Question

F is the midpoint of GH Point G

is located at 32 and F is at 105. What is the location of point H?

Answer 1

105-32=73
105+73=178 is the answer

Answer 2

Midpoint equals the average of the two coordinates.

F=(G+H)/2

2F=G+H

H=2F-G, given that F=105 and G=32

H=2(105)-32

H=210-32

H=178
